We were camping because we were attending Telluride mountain film festival and we did not realize that we would be in for a great surprise. we camped for 3 very long nights at sunshine. the bathrooms were the usual hole in the ground, i'm not complaining because that is a luxury. We went at the end of may and we ended up incredibly cold all night. as we were in the grand canyon a few nights before. the camp groundsman was very nice and we did pay our dues. i think 18 is the right number. we may have payed 15 because we were not using the hookups. you will wake up to an amazing view of the mountain range that is actually on the front of the coors cans( as told by a telluride native). Just BE AWARE that the weather in Colorado is unlike the weather anywhere else. it is bi polar.
