Played a course in Vegas a couple months ago . Really good course . Except the bunkers . They were literally clay , and were cut with huge ridges and set well below ground . I think I carded a 27 on the parthree 16 th when my tee shot landed in a greenside bunker I can get stubborn . Not even exaggerating , a legit twenty seven on a par three . Kind of ruined the day to be honest . How does a course in the middle of the desert not have sand ? <| sep |> Someone can correct me if I ' m wrong but I ' m pretty sure it has to do with the fuel coming out of the nozzle not having enough oxygen to burn correctly , the spray has to spread out enough that air can mix in and combustion can occur . <| sep |> I only see the tan and grey . Which other gold cups are available ?
