and lived at Splashdam, we walked from there to Bartlick. I remember the tunnel there and a train came and were in it...I was scared to death but there was some sort of places cut in the wall and you could step in and hold on! The sound was like those you hear on tv during the tornado scenes..but I'd do it again in a heartbeat! We also canoed down (before it was the "in" thing to do) and there was a waterfall - which we didn't know about until we were right on it - that was neat, too.
