I live in the St. Louis area and am always looking for new folks to ride with. I actually haven't ridden much locally as of late but St. Joe is my 'no better place to ride spot'. Gnarlykaw, H20, Colemanapp and a few others are local also. I haven't yet had the pleasure of riding with colemanapp but plan to do so as soon as I'm not on the road and it's above freezing. Gnarly and H20 go to St. Joe fairly often and are great riding buds. There are also a couple others (non DRN members I believe that usually hook up with down there.)
Every once in awhile a few DRN'rs from parts such as Iowa, KC, Kentucky etc. get to drop by for a ride.
Drop me a line sometime and we'll try to meet.
By the way - where is Grindstone? trails or track?
