Can you just pick the stuff up at Lowe's or Home Depot?
yep.
I work every Saturday night and I'm not sure I'll be able to make it back in time from Brooksville
Volunteer for an early work assignment - like helping with course set up, or tech, then your work is done. You can leave whenever you feel like you have to, and won't make anyone upset (except you if you don't get all your runs...)
Sept. event IS a Sunday!
