If you ever get stuck in Las Vegas for a week and have the $$ stay at the Mandalay Bay and bring your goggles and running shoes. They have a 50m wide wave pool for laps that has swells and currents, and an enless river to swim upsteam against. Running south out of town on Las Vegas Blvd there is a Major intersection at one mile intervals for 3-4 miles for a nice out and back. Too bad I couldn’t convice my wife to let me bring my bike.
