Gerry,
Mistake?
Only if you don't really want to go...
Vegas may be a little cool, but always a welcome change from the Midwest.
It is quite a long drive, but if you have the time, why not.
There is a lot of beautiful scenery, and other than high passes, the snow isn't an issue unless they get a blizzard. Folks in the Rockies get a lot more snow than we do, and deal with it well.
You might consider a more Southern route home, so that you can tour the Grand Canyon, and come back up through the mountains in Colorado on roads other than the Interstate.

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
