A campground close by is nice. We do approx 90% of our camping at a state park less than 20 miles from the house. We have a pontoon boat at the marina, so everything is pretty much in place for fishing and boating activities.
Like you said, it's like a different world. Makes it nice for people, like my wife and I, who work all week to be be able to take a short drive and still feel like we're getting away from it all.
