This will be our 4th year. We have never had any problems with them running out of water, ice maybe, but not water. The weather forecast looks like it will not be a scorcher this year, Yea! We have never had a problem getting started. Just get there early and get toward the front. We barely missed Hell's Gate in 2006 because they closed it so early! I was not happy! It didn't feel that hot to me.
Have fun and be safe!
