I think it would have to be in heats, depending on how many people showed. Much more then 3-5 people and you are asking for huge safety risks. There are a couple tight lines in there that could get seriously nasty if more then one person tried to go through at once. I do think it would be lots of fun and a good spot for it. The only downside is that the road is narrow there and wouldn't hold a crowd very well, so it would have to be low key. Not sure about permiting and such either. It might have to be one of those non-official races. Not sure what it takes to get a race going there officially. You set it up and I'll be there to run safety or spectate. Good safety would obviously be key if you are gonna do this. I'll be interested to see what others think.
