barb/ed's cambridge hills street-o. started and finished at cp3, nearest my house. only hiccup was when i tried to hit cp6 from the south and was met by accurate mapping. i assume street-o club only has two rules: getting hit by a car is a DQ, and run on the streets, eh? broke that rule a little on the way in to 6, but i was honest on the way out. only quirk to the route was having CP1 down the one-way-the-other-way major bus egress from the harvard square warrens. danger-fun!
poor substitute
