How about air tight tupper ware boxes and put in some dessicate packs. I saw where Wal-Mart was selling cans of dry-sorb in their marine section the other day. Also I'm pretty sure Lowes and Home Depo have something similar to the dry-sorb canisters.
Plano also makes a water proof box with a rubber seal if you're worried your fishing buddies will poke fun at you for using tupper ware.
