After a 6 year hiatus, I spent 15 mins in the vegas tunnel. It was awesome! after the first 6 mins things were feeling very stable, on the last 3 min session one of the instructors & I were up flying together, up-down L-R, Side to side & shaking hands. Again it was awesome. I only did 42 jumps through 04-06 but never forgot what I learned. Also I was stoked to find that there is now a tunnel in delta BC. So I intend in the next 1-2 months on an hour with a coach so I can start back flying. Tunnels are sweet!
