Corn Hole? this game from the underground turns out not to be so underground

it seems that people are playing Corn Hole everywhere all the time
it does not shock me that this game is so popular with the frat boys
they like it because they can play it with a beer in their hand
and well
although tailgating is not my thing
I do think I can see the reason why they get such pleasure from playing corn hole

the question...
do you let the mail carrier bring the corn hole bags in his mail sack
or do you make your own corn hole bags instead?
