We use maps and tips and road logs from many sources. We have been using Mike & Terri Church books and their website for years. We also use Bill & Dot Bell's ontheroadin website and bought their road logs. We have the logs in binders and we can follow and have room to add our own notes and landmarks to keep the logs up to date. Mexico Mike also sells maps on his website - and the site is full of lots of other info and tips. We find these logs and blogs and websites to be very useful and worth the cost. We also put maps on our blog. You can use all of these sources to find RV parks and other places to park. There are many other useful sources out there. We have never traveled with others - not even for a day - though we do often make plans to meet up with people who travel some of the same routes.
