I do not recall which Rick Steves newsletter this information was in from earlier this year, but I recall Rick mentioned that he had an interest in potentially putting together another bus tour that goes across the continental United States. I have travelled through a fair amount of the US for my age (I'm in my mid-20's), but just wanted to make a post to say how I thought that was an awesome idea. I think Rick should really consider offering that tour, when it is safer. Especially with the pandemic and air travel, a US bus tour could be possibly easier to arrange. It could really be fun!
But that's just my two cents! :)
