1st Round: THREE DISCS ONLY.
Carry only three discs, no swapping, no replacements!
2nd Round: You get your bag back!
Mulligans for sale: $1 each, limit 5 per round. Tee-shot only, mulligan throw must be used.
Out of curiosity, what are the rules for the mulligans the first round going to be? i.e. Can you go get your errant throw/disc to re-tee? Or do you need to throw one of your remaining two discs? If not, that'll make using mulligans pretty rough the first round (as I'm guessing most players will be bringing a fairway, a mid, and a putter).. but otherwise it'll possibly slow the pace of play a bit.
