I have no problem with a pro using this resource and have waited an hour on more then one occasion to get water because two Pros were in front of me. We do not have any exclusive right to it, any more they they do. Sometimes I pick up water for my buddy and he pays me a few bucks for my time. Does that make me a professional? From what I remember Sand Bar sells there water pretty reasonably @.39 a gallon. I think that is far considering how long it takes to run down there, fill the containers and then transfer it to their tanks and then store it and be open store hours, so you can get it when you need it not just during a short time window. Now if they were selling it for $1.59 a gallon that would not be reasonable.
I have a much bigger issue with people stealing or causing a fuss and interrupting the operations there. That will close it for all of us.
