Frankly my take is one pass one vehicle not one pass 2 vehicles so what is actually the difference whos using it on any given weekend. All I see them doing with my cash is improving the small paradise the BLM parks all their utvs atvs rails campers trucks etc on and not much comming back to us so If I want to lend my pass to a friend or family member when Im NOT using it whats the difference? its good for the whole season one vehicle at a time no matter who is using it.. JUST SAYN....
