hello chewy, thanks for the reply to my introduction. My first message, I hope you receive. Funny thing you should mention terrain, I went to a trials meet in Meriden, Connecticut on 10/25, about 100 miles from my home in newport, Rhode Island. I couldn't help but notice the stones and ledge there. Everywhere there were these 1/2 brick sized rectangular pieces of ledge stone. All this made riding more challenging, as they were covered in leaves, and completely wet from a torrential rain storm the night before. Our area in Exeter, Rhode Island is all granite boulders, mountain sides in some cases. I have good pics and video of both places: ) with regards, rr
