The 32 oz Panera tumblers (the ones my friend Lucky and I buy our drinks in) are my current favorite method of iced beverage transportation -- huge, sturdy and will take four or five refills before starting to look (and feel) gross. Florida Summers are pretty much synonymous with never willing to be further than an arm's length away from what's essentially a 1/4 gallon of flavored ice and a straw.
