So we are leaving for this trip on Saturday (wife and 22 month old son), not backpacking, all hotels, sites, scenery, day hiking. Weather reports look like shorts and tshirts, maybe a fleece for early morning activities but then the "Grand Canyon, AZ" report says like high 90 low 32. Is that low like at the bottom of the Grand Canyon at 3AM or something? I am confused.
I am tempted to pack all shorts and tshirts with one pair of jeans and a fleece for chilly mornings/evenings but then that low temp is making us bring all these extra layers, gloves, fleece hats, extra long pants, etc.
Are we being crazy? I feel like we are packing all these winter clothes for the hot dessert in late May seems kinda nuts. We have never spent any time out that way though so we are complete newbies.
Please advise, thank you.
