Moab is a great town. It is full of people that are friendly and non-judgmental. If they are treated with respect they'll return the courtesy.
Many residents also feel their town has been turned upside down in the past few years from tourists.
While this isn't the lone fault of bikers, we are far from blameless. It may seem innocent enough to go in and fill water bottles at a store, but the shopkeepers aren't in business to wet the innumerable whistles of visiting bikers. Always ask before filling bottles and only if you buy something. Better still, the bike shops are more understanding and willing to help. There are some public places to fill up.
