I am in Arizona. My 12-year old brother Ira and I made the cross-country trip from TN, he is spending two weeks with me in Tucson. We have been mountain biking twice, toured the T-rex Museum and the Sonora Desert Museum. He has watched a lot of TV while I have been out on my road bike (he loves my DRV).
I have attended group rides with great riders and found perfect base mile routes to ride alone. Tucson is the most cycling friendly city ever, there are bike lanes on almost every road and the traffic is very courteous. The worst thing anyone has said to me from a car is "good one" when I went through a yellow light. They even have a bike lane on part of the interstate (I-10). Oh yeah, it doesn't rain here. The weather is picture perfect, sunny with highs in the high 60s/low 70s with no humidity (your clothes are dry even after a long ride). Last week I got in ~14 hours of on-the-bike training. Feels good to be taining again.
