First time going to a Red Rocks show in March — what should I expect & what’s the best transportation?

We are from Texas and will be attending a Red Rocks show in March and we read that the weather can be unpredictable. For those who’ve gone that time of year: – How cold does it usually get at night? – Is snow common? – What do people typically wear? – Best footwear? Snow boots? – If we are not used to driving in snow or mountain roads, is the shuttle recommended or Uber?

Any tips for a first-timer would be super helpful! ☺️
