We stayed at the Nellis site for 1 night and moved after that it was so bad. Relatively clean but NOISY. Major trafdic, cars racing, sirens all night. Who empties trash dumpsters at 6:30 am?? And for the price, put in a WiFi booster for cripes sakes.It stinks even in the pool area and can't get it at all anywhere else. Sites are all gravel and level at least but definitely not up to KOA standards.
