Does anyone own a swing set and have a sloped yard? We want to purchase a playset for our kids but I think we would have to level off part of the lawn first because it slopes down as it goes away from the house. My husband thinks we could just dig out where the posts go and install those to be level, but I think the whole playset area needs to be level. Anyone know what to do here? And if you paid a company to level an area what was the approximate cost? Thanks!
