Re: Rocky Mountain Ride
I would not hesitate to schedule a mid-September ride in Colorado. Sure, you might hit some weather, but then again, you are more likely to encounter the absolutely most beautiful, pleasant, moderate and delightful weather of the year. I have divided my time between living in Denver and Steamboat Springs for almost 20 years and especially in the mountains September can be the most beautiful time of the year. In the Rockies you should expect day time highs in the mid to upper 60s and evening lows in the mid 30s. September is also traditionally a pretty dry month with average precipitation of about 1" for the entire month.
In planning, you would want to consider options, however. For instance, if you plan to include Aspen in your trip, while making the trip into Aspen over Highway 82 (Independence Pass) at 12,100 feet is gorgeous, you should have an alternate route in mind as well. The same is true in other areas. Denver to Steamboat Springs through Rocky Mountain National Park over Trail Ridge Road is a real treat, but it is generally one of the first roads to get snow, so plan an alternate. I hope you do plan the trip for September. Based solely on annual temperature and precipitation averages, you will be delighted you picked the Fall for your trip.
