We not only camp but love traveling by Amtrak. Several years ago we followed my brother's lead and got an Amtrak Master Card. Almost all purchases go on that card and we pay it off every month so we pay no interest. We have been able to take one trip from Cleveland to Portland Oregon to Sacramento and back to Cleveland on Amtrak points. When I retired I took my secretary to Glacier Nat'l Park and the only cost was accomodations and rental car while there. Next week we are going to Washington D.C. for a couple days. This is not for everyone but we enjoy it.
