I'm going on the 2015 Antarctica trip and don't see a simple packing checklist. What to bring? NOT to bring? Weight limits? Why have I read, to not bother bringing a tripod (that one really baffles me, I know you can't use them on a Zodiac, but aren't we on shore at various times?) Any help from "you'all" that have gone on this trip recently would be most appreciated. Thanks Jeff
