Hey, this is next to my house! I always take Shady to get home from that area. It seems to be the least hilly of the hills, and wide enough in most parts for people to pass safely.
Highland, left on Alder, right on Shady...
Shady to Forbes (right turn - now with sharrows... oh yea!)
Take Forbes to Wightman St (left turn - bike lane!)
Wightman to Beacon (right turn - another bike lane!)
It is all downhill from here.. Go down Beacon, turn right on Hobart/Panther Hollow (whatever it is called) when you get to the end. Make sure you get in the left lane.
Take a left onto Greenfield Rd at the stop light, then go all the way down the hill and across the Greenfield Bridge.
Take an immediate right after you get across the bridge, before the stop light. The street name is Alger. It turns into a one way after a block, but you can either get off and walk down to the school on the sidewalk (or ride really carefully?), or turn left then right and take Greenfield Ave a few blocks to the school (turn right at Lydia - there is a stop sign).
