To the OP: Best strategy; get inside a metal cage (like a bus shelter) when electrical activity is most intense. Fallback position; make sure you don't fall if you are struck. Much injury from lightning comes from the fall after the strike. (I've no source for this assertion.)
I've worked with (extremely) high voltage (AC) electricity for around 30 years. Suffered a hit about 29 years ago, 200kv fortunately at only 30 amps and even more fortunately, it stayed on one side of my body. Most excruciating pain I have ever experienced. (Most lightning victims are knocked unconscious. I was not so lucky.) Then, of course, I moved to a small island in the middle of the squall prone Chesapeake Bay. And switched from bamboo and fiberglass to carbon fiber graphite fly rods, while standing in a small aluminum jon boat. My dock was hit almost weekly. Three times during one hurricane.
Here's some of what is known about lightning and humans. If you are struck and survive, your odds of getting hit again rise ridiculously, to the extent that it's almost not silly to say; you will probably get hit again. Seriously. It's a curious phenomena, and no credible theory has been advanced as to why this is so.
If you can't take shelter in a metal (Faraday) cage, standing in the open is not advised, nor is standing near trees. Crouching among shrubs or lying in a gully doesn't work either. (A couple at a marina near where I lived at the time tried laying down in a ditch among shrubbery, and were fused together. Icky. She died too, after a few days.) With all those masts, one would have thought lightning would have originated from them? For the most part, lightning starts from a ground source and discharges upwards. ("Positive lightning makes up less than 5% of all lightning." http://www.electricalfun.com/lightning.htm) So, resting on an insulator might afford some protection. Remember, most injury results from the victim's fall, so sit or at least crouch.
And no smoking. The Navy did some model rocket launches near my residence and discovered the rocket's exhaust cut a conductive path for lightning through our normally insulating atmosphere. They were using rockets with long wires unspooling beneath them to attract strikes, and when one wire broke, found rockets without wires worked just as well. So, if you want a real bang up 4th of July, launch a rocket into a t-storm. I've done it (from a distance) and it works.
Of all of nature's spectacles, lightning is the one I'll anthropomorphize. I have my doubts about hurricanes and tornadoes, and for good reason: hurricanes "seem" to be drawn to me, and I know a guy who "appears" to attract tornadoes. Lightning, however, is idiosyncratic, capricious, and can strike from a clear blue sky, much like love. http://www.straightdope.com/columns/read/2683/have-people-actually-survived-being-hit-by-lightning-multiple-times http://www.uic.edu/labs/lightninginjury/ltnfacts.htm
Though PA is one of the top ten States in lightning causalities, perhaps you'll find solace that "Men are struck by lightning four times more often than women"? http://science.nasa.gov/science-news/science-at-nasa/1999/essd18jun99_1/
Fretting doesn't help too much, but having a plan may. Hope this is helpful.
Of note, though the literature describes "...injuries to postal and construction workers and persons using telephones that have not been properly grounded. The numbers of farmers injured has decreased farmers to work larger fields in better-protected vehicles. Injuries during recreation have increased. They occur to joggers, hikers, and campers, as well as golfers. In addition, a significant number of people are injured while participating in team sports...", there's scant, if any mention, of lightning striking wheelmen or wheelwomen. (http://www.uic.edu/labs/lightninginjury/ltnfacts.htm)
One incident is rather interesting: "The most well-known death during the spate of Franklin imitators was that of Professor Georg Richmann, of Saint Petersburg, Russia. He had created a set-up similar to Franklin's, and was attending a meeting of the Academy of Sciences when he heard thunder. He ran home with his engraver to capture the event for posterity. While the experiment was underway, a large ball lightning showed up, collided with Richmann's head, and killed him, leaving a red spot. His shoes were blown open, parts of his clothes singed, the engraver knocked out, the doorframe of the room split, and the door itself torn off its hinges." http://www.electricalfun.com/lightning.htm
Notice the Professor was afoot. Had he been biking, he may well have survived!
Ride fearlessly.
