September brings magnificent fall colors to the Aspen area. A drive up Highway 82, towards Independence Pass is glorious.
Independence Pass has a relatively short season, open only from late June til late September. But the every month has it's special look.
Even great in the summer
"Native - Not a ski tourist"
Aspen is famous for all those jevenile ski bum movies, serial kill Ted Bundy, and the bizare home of entertainment's original Rocky Mountain High jet set (pre Telluride.)
But all snow melted, it is a great place to visit during the summer!
