Ignore the bitter trouble-maker reviews, would you really want to camp next to those people? I stay here every single time I visit family in Marshall. When you call ahead (and there's almost always a place you can park, even when it's busy since they try to leave a few gaps here n there) let them know if you are wanting to cook out, stay up late, etc. One end is a little later awake than the center where the long term and quiet young fogies like myself want to sleep. YES they only take cash, maybe a check if you are around a while.
Cooking the books? what a rude insinuation that gal made. What ever happened to traditional values and establishments that don't require a credit card and multiple i.d.'s? This place is more traditional, conservative values than any place you'll visit.
Clean. Keep it clean.
Friendly. Behave yourself and relax knowing others will as well. The honey wagon is awesome. He even checks and trouble shoots and is super knowledgeable. This property is surrounded by water (hence the Tri Lakes?) a sewer system throughout all the little meandering drives and water ways wouldn't be even remotely reasonable.
Ignore the nay sayers, come stay where the trees are big and shady, the neighbors are chill and accomodating, and the dogs are always as happy as the children.
