Trip planning in progress!

My fried Max and I are in te stages of planning a motorcycle trip to Colorado at the begining of summer. I have been to Colorado several times and think it will be a great motorcycle trip. Max will be riding his BMW R1200 GS and I will be on my BMW R1100 RS. The hardest thing to plan will be what to take. I'll be posting some of my planning thoughts as well as welcome comments from you experienced riders.
