Yellowstone Grizzly RV Park

Very dissapointed with the condescending owner? Manager? We made reservations.....we told them we would be arriving late! We arrived at almost 3am due to the roads closed on 191 and a large detour. We had 2 spaces for us and our grandkids. Unfortunatley one of our vehicles is a deisel. When we pulled up a man claiming to be the owner came storming out of a building yelling at my son to shut his truck off, you are not taking that noisey truck into the park. He then made my son and grandkids park their truck and camping gear out in the eneterance and said we should have been here by 10am. We had to load all our kids and grandkids into our very small class c? I told him I would be yelping his behavior and he quoted "oh your going to try to black mail me for a discount" I explained that I had told them we would be late and there were major road closures? His comment "Road closures are not our responsibilty" I will now use the koa down the road....
