This turned out to be the final camping trip of the season. The days are getting shorter and colder, but the Fall colors are peaking, and the aspens are ablaze across the mountainsides. It is my very favorite time of the year. The air is crisp, and the sky seems to turn an even more brilliant blue than normal. It is also the time that the bull elk begin to bugle during their Fall rut. Their eerie calls echo across the valleys at dusk, and the bulls can often be seen fighting each other and competing for mates. It is a great time to visit Rocky Mountain National Park (RMNP) and take in these sights and more.
