I just got this in the mail and am disturbed by it. The State of Wyoming Fish and Game have found a way to get more money from boaters. A 2010 Aquatic Invasive Species Boat Decal Stamp is required. It appears that the resident boats are different from the non resident boats thus the cost of the permit is quite different. Now I know that I won't take my boat to Wyoming for vacation. Check it out!!
