Like BB_TX, we use KOAs, Good Sam CGs and other CGs (even state parks on occasion). Lots of choices if you don't limit yourself to KOAs only. There are plenty of KOAs; some older ones have left the KOA system but are still decent parks to choose from. RVparkreviews is a great resource if you have access to the internet while you're traveling. A KOA directory and a Good Sam directory (book form) are also handy. (Why not pick up a KOA directory on your outbound trip? They're free and you can get one at the first KOA you visit. They'll have an updated list for this year of the CGs in their system.
