My image of riding along the canal is cars and more cars.
Riding on the Canal Road is car-free. It's a multiuse trail, so there can be walkers, bladers, etc. We could also ride from the canal on some not-too-busy roads. The busy season does not really start until the schools are out in late June/July.

I would also be interested in riding up in the Concord/Carlisle area if that is more convenient for others.

I am going to Coyote Hill in Fairlee,Vt June 16-18.
Imperfectstorm...That is so cool! I really want to do a mtb skills camp. I was looking at that weekend, but it is too close to my return from my California vacation next week. I'm thinking about maybe doing the one in August. Let us know how it goes! A trip to ride up in NH sounds good, too.
