Looking at taking a road trip....
March traveling can be somewhat chancy in Wy/Colo/Neb with the possibility of ice storms/snow storms. I lived in Colo for about 4 yrs and still have relatives there. I suggest going to Loveland and up to Estes Park - - and all the way up (But wait! Not in March!).. LOL So maybe head down South and stay out of the mountains and visit the Royal Gorge! That's fun! Wait! Are they open with Covid??? Better Check! Wyoming is beautiful! Grand Tetons and Jackson Hole! Yellowstone! Cody is a beautiful town! Not sure March is the right time, though. Hmmmmm
