Canyons end of May - how to dress

You are going to the wild west; there is no need to dress up in the evening whatsoever. I did find that the mornings were chilly for me, and I always always and always bring a pair of gloves, a fleece, and some sort of windbreaker if need be for over the fleece, a backpack, sunhat and a warmer type of ski hat. I used them all at various times from t-shirts to long sleeve tops. Yes, you'll experience all types of weather. I brought athletic/hiking shoes, sandals for outdoor walking for any length of time. The only time I came close to dressing up was for the farewell dinner only because we were in a very nice hotel, and I was getting bored from outdoorsy casual attire. The desert is very dry. I'm a contact lens wear 24/7 and I had to find moisturizing eye-drops when I didn't think of bringing some.
