We started out in a 17' 1970 Aristocrat Lo-Liner towed by a 1969 Buick GS400, with three kids ranging in age from two to seven. Our longest trip was from the SF Bay Area down to Las Vegas, across to Albuquerque, north through Denver and on to Yellowstone before heading back west on I80, and ending up at Tahoe for a week. Rain chased us everywhere, but having that snug trailer after a disastrous Oregon coast tent camping trip the year before sold us on trailer camping.
We hit every zoo on the itinerary, museums in several places (including the fabulous Museum of Natural History in Denver) and watched Old Faithful from under the protection of the Old Faithful Inn. We met many wonderful people, and the kids had a great time getting to know other kids who were traveling. It was only after we got home and turned on the network news that we realized that the family we were chatting with while waiting for the eruption were a national news anchor and his family.
You meet the nicest people!
