We've been to Rocky Mountain NP for short camping trips the last couple of years and may go again this year. My luck hasn't been too great for successful photo excursions, though.
Two years ago it rained the whole weekend and this last August I tripped and fell and cracked a rib the first night there. I snagged some good shots both trips, but not nearly as many as I wanted to.
This next time we were thinking of later in the season to catch the changing aspen. When is the best time of fall to do that? Late September?
I live in Kansas City and I envy you folks who live in such scenic areas. But if you are ever in this area, let me know and I can show you some great Barbeque!
