I'll have just a day to spend in the SLC area, looking for recommendations on what to see and do, including visiting mountain areas such as Cottonwood Canyon, and what to do there as well. Will be there May 12th. Will have a car rental, and wish to see and do as much as possible in a day. Looking for suggestions and ideas on how to fill my day. Also, any evening suggestions? Thanks, I appreciate your help and recommendations.
