Thanks to whoever gave me those cards! :D

GUYS PLEASE, I NEED 6 MORE SUMMER ADVENTURE TRADING CARDS SO I CAN CRAFT THE BADGE. MY PARENTS WON'T LET ME SPEND ANY MORE MONEY ON STEAM FOR LIKE A WEEK AND THE SUMMER ADVENTURE ENDS ON THE 30TH...PLEASE TRADE OR JUST GIVE ANY EXTRA OR UNWANTED CARDS TO ME. I CAN SELL THEM AND GET SUMMER ADVENTURE ONES. IF YOU SEND ME SUMMER ADVENTURE CARDS I ALREADY HAVE THEN I CAN JUST SELL THEM AND GET ONES I DON'T HAVE. Thanks...Boa

What? I forgot it...go home now.
