Hi I am planning on taking a road trip to Breckenridge, Colorado coming from St. Louis, Missouri. I was wondering what is the best time to go on this trip and if there are any points of interest that I should know about. I plan on going to the sand dunes, mountains, etc. I was also wanting to know if anyone had any good places to see on the trip from St. Louis to Breckenridge. Any other help would be appreciated.
