I figure 40degree temps would be as low as I would want to ride in (This is about as cold as I ride my bicycle in). You don't have to worry about rain so much is AZ either . I know if I rode a motorcycle regularly I would inevitably get caught in the rain.
Yea we can see the rain coming here cause it's so flat. And if there is a 30-40% chance of rain it usually doesn't rain until im home from work. All though I am bound to get caught in 1 or 2 dust storms a year which isn't going to be very fun. I will problably pull over and just wait it out.
