I brought up getting bags of crushed ice before in preparation for a luau. Crushed ice is as much a part of a proper tropical cocktail as fresh mint and rum. But when you are mixing for 40, it’s hard to get that much proper ice.
I found a new solution. Sonic Drive-Ins. They are not in all the country, but they are pretty widespread. And that fine ice they use for their drinks is available by the bag. That is a great solution.
