No expiration, no fine print other than you have to let me know a week or so in advance, yu must remain in good standing on AW, and I prefer Alaskan Amber. If you show up with Pabst, Coors or anything in a can you'll be shown the door soonest.
I don't anticipate on having 10 AWs' show up to fly so I think you're safe.
After May 08 would be best. I'll be in the desert until then.
Mike-
Everything sounds good, except there's a chance I'll be in the desert after May 08. Maybe just to say thanks for the offer, I'll drop some cans of Natural Light and Tab at your place before I go.
