Hi Steve was listening to you saying you don’t take your coat off because of the sun. Well I’m the same or I’m allergic to the sun. If you purchase a sunscreen called p20 it’s a total sun block and works a treat. I used it in Portugal it was 42degrees and I was walking around in the sun for a week and didn’t get and blistering or burning first time I’d risked being exposed in 15 years and it worked a treat.
If you see this your Vegas trip might not be to hot for you.
Kind regards Brighty
