Gardening Galore

I am getting ready to head out for my own personal garden tour and then Steve will drive me in the Jeepster to work as a greeter for the Maricopa Master Gardeners "Real People, Real Gardens" tour. That should be fun but I'm worried it will be too hot. My MG shirt is red and HOT (I think I am going to order a t-shirt) Hopefully my face will not match my shirt all day with potential heat stroke.
