I too enjoy the cans, cheers.
Just FYI, New Belgium, Makers of Fat Tire Amber Ale (and several other belgian style beers) supports the following:
The Range Life
Whitewater of the Southern Rockies
The Mountain Buzz
Canoe and Kayak
Fibark (and a dozen or so other river celebrations including Gore on occasion)
Save Our Rivers
Save the Poudre
The John Waterman Colorado River Project
New Belgium's also conserves water when they make beer, ultimately cutting the industry standard for water use in half.
Point being New Belgium cares a great deal about rivers, water and access.
Is there another beer maker that puts this much energy into the rivers we love so dearly?
