Now that you brought it up....YES, we've had the same problem!!! The incident that really got my goat was at a "viewpoint" in Utah. We were pulling our rig, BIG lot, with cars to the left and RVs to the right. Had a guy pull in ahead in a rented Class C, and STOPPED right at the "entrance". We couldn't get by and we blocked everyone for both areas! We waited for him to move, he didn't. I finally got out and found him taking pictures and informed him he HAD to move his rig. Yeah, he did, but he gave me such an evil look! HAH....he has NO idea the looks we were giving HIM!
