Camping disasters are the sole domain of KOA's. Last June we arrived at our site booked months in advance at Sequim, WA State Park. After a long day on the road we pulled up to our site smack dab between a large church group of 45 people and had to evict half of them and cars out of our little corner of "paradise". For the next 2 days, we tolerated frequent incursions since the shortest distance between their two campsites was through ours. Their campfire fuel was pine drug out of the woods and old tires and the language of choice was an foreign dialect best spoken at 110+ db. Not even any tv or XM reception to drown them out. Really nice people BUT really LOUD, lots of free range kids and up late! After 2 nights of that, I couldn't help but hug the nice elderly couple that pulled in next!
The Rangers were less than worthless.
The moral of our adventure was to always have a back up plan, in this case: earplugs.
