Q: how do I find the main loop? Is it marked with blazes? -Miwako
A: Park at Nassahegan Ball Fields. Ride away from Punch Brook Road behind baseball fields - the White trail is back there. It heads East and turns South toward Stone Rd. Keep following to Red/White signs. This leads back to Miller Rd/Punch Brook. It's pretty well marked, but loading Strava will keep you on track. There's lots of white/white trail markers that can be confusing. In general, the main path is well-worn, so keep going on the widest white path and you'll stay on the main loop.
