being as I always end up as the boat captum I save the beer for home, ussually 1-2 gallons of water on ice. several pepsi's for real early ( wakes me up and keeps me from having to head for the john during prime bite) then I'll switch over to water after 8 or so. bottom liine, sitting in an aluminum boat on the water when the temps what 80 now? not good to drink much of anything but water, and really not good to not have any on board in case of a break down trolling back to shore can sometimes take a while \:\)
