As mentioned, very doable. I get the "stop and smell the roses" approach, but we enjoy the view from the bike. We did West Yellowstone to Sturgis easily and stopped plenty for pics. Old Faithful, Continental Divide, etc. Also as mentioned, it can get cold. It was August and we froze our butts off in the morning (7 am). But, there were hardly any tourists on the road through Yellowstone so it was well worth freezing. I would bring the heated gear.
OK, Bob, I caught you. (Maybe) Either your computer is working OK now or you're still using your Galaxy. Hopefully your computer is working and I did in fact catch you. It's time to continue your ride report, not spending your time replying to others. We've waited long enough. Even here in Texas we've been having un-rideable weather, so let's get on with your report.
Apologies to the OP for getting off subject.
