Airfare to St George Utah - varies from the starting point but booked far enough ahead say $350 round trip.
Hotel is going to run $140 single $80 double occupancy - (Kanab UT pricing)
Rent a car for a full size SUV - 4 adults w/ gear is $80/day.
Food? per day $40 gas $15/person??
So Airfare + $130/day to 200/day??? 4 or 5 days depending on the shooters - This is mid September pricing.
Could save some $$ at a flea bag hotel but....
The shooters are the boon and bain. I did this alone in 2013 and while it was fun, it wasn't as fun as it would have been w/ others (Daughter was too busy )
