made several trips in younger days from Ky to Co for snow skiing. drove all over Wyoming, parts of SD and parts of CO a couple of years ago (couple of times for thanksgiving weekend, more driving than skiing). driving across Kansas is torture during daylight hours, nothing to see and flat. another family trip, flew into Vegas and drove all over Az. depending what you want to see, may be worth flying part of the way. some complain about flying, I've had very few issues.
