We are on for Saturday, 9AM!
I hope BikingGirl and her tribe and others can join us. Safe to say we are all adjustable in ride length and speed.
Alert rider Jim points out the route I posted didn't go by the Cow Tunnel which was the whole point of casting off from Fern's. The tunnel is ~200 ft past the Towle Field parking lot on the south side of Westford Rd.

This corrected version comes to 41.5 miles

Yes, Fern's is the general store/coffee/deli across from the library at the rotary.
