We were at Calvin's for 4 nights 2 different times in May. We were there in our 35' trailer. Our site (14) was shady and paved. The pull-through sites were all paved. There is also a dump station next to the office. There is a storm shelter (which we had to use one night!) with a bathroom. Be prepared for local train activity 3-4 times a day but you get used to it. A GPS will not find Calvin's correctly. In Wamego you will travel on 4th street past the city park. Once you get to the industrial section and Caterpillar tractor company Calvin's is just past the row of trees. We camped here in a Travel Trailer.
