Seven. Absolutely gorgeous day, temps in the high 70's, sunny, very little East wind. Started in Ottawa, out and back ride to 6 miles East of Seneca. Good speed for a trail ride. The I&M has fallen into very poor condition, at least on the portion from Ottawa to Marseilles. East of there the condition is much better but there are a lot of fallen trees that the State of Illinois - IDNR - doesn't seem interested in cleaning up. Still very fun with long sections of curvy single track, gravel and double track. Still very beautiful scenery, although slowing down or dropping down below a certain speed invites mosquitos and black flies. Stopped at Tangled Roots Brewery in Ottawa for rehydration afterwards - very nice.
