In the early days of my festivation the wise thing to do was rent a pickup truck from budget, they had great deals back then, and my old toyota 4wd was on it's third head gasket. Any way I unloaded and parked where I was directed and then promptly forgot about it until Monday morning. Well you can guess what happened? Not only did I not remember where I parked, I could not even remember the color or license of the rental. Now THAT was an adventure, fortunately it only took about 4 hours to find the truck ;-)
There is plenty to explore around Telluride within walking, biking, or free gondola ride distance. When I park my car after unloading I never think of it again until the Monday after the festival trying to remember where the hell I left it.
