We stumbled upon Green Acres RV Park on a trip through Minnesota. It is handy to interstate 90 at the Dexter exit.
The campsites are large and level. Ours had 50 amp service and most sites are drive-thru. We really appreciated the good Wi-Fi service (free) that we got there. There is a truck stop a short walking distance from the park. It has a full service restaurant, as well as a grill for pizza etc.
Our son caught a few fish in their pond which he thought was lots of fun.
