Trying to weed out stuff I really don't need to get suitcases a little lighter...some of the things I'm wondering if I'll really use or not...insulated cups with lids and softside cooler, thought I might want to take beverage on the beach and a few in a cooler, anybody have opinion on whether these are necessary or not? Binoculars are another thing taking up some room that I'm not sure are necessary. Any feedback? Thanks.
