I'm going to the Stampede for the first time with my family!!

I am in search of coupons distributed by Coca Cola in southern Alberta for admissions to the Calgary Stampede. Specially marked 12 packs of pop may have b1g1 admission, or b1get1 50% off....if anyone has these or has seen them please please let us do a trade! I'm heading to the Stampede in July & would like to cut costs wherever possible as I hear it's very expensive there!
I've also read that the Travel Tourism info centers have a coupons for the Calgary zoo inside. If anyone lives in Calgary & could mail me this promo I'd return the favor with a generous trade!

PS...any tips for surviving the stampede would be greatly appreciated. Our children range in age from 5-15 (blended family)

Thanks so much Canuck-r's!
