On our first weekend out in our NTU camper, hoping for some needed decompression time as a couple, we got a call on Saturday AM from my FIL. He lives 30 miles from the SP where we were camped. He said he was going to stop by and introduce us to his new lady friend. A few minutes later he called again and had invited my BIL and family to come too. Who does that? We made a quick run to get more chips and beer. They arrived at noon and left about 6. We love them and love to share camping but this was wholly unexpected. They brought no supplies. It was not the day we hoped for when we booked six months before. Anyone else had unexpected guests show up at camp?
