Looking to do a road trip over spring break from Jackson, TN. Any ideas on where to go?

Keep in mind that it's early March and while time probably is not much of a factor, money is. I'll have, at best, about $500 available. I'd like to go to Colorado but have no real idea where to go, what to do, if this is possible, or if this is a good idea based on the weather. Any info would be appreciated!
