I must've been adding metrically.
Just keep in mind that not all Target stores will carry the exact same items. There are obviously other retailers that stock them, it's just a matter of finding one. There's probably a retailer finder on the Igloo site.
If Steve comes up empty and you still want one, like I said, it's possible that one of my crew will be able to bring one in June, depending on who's under the checked baggage allowance. I'll be at the limit, though depending on how things go and if you're still in need of a non-wheeled 50, it may be convenient to leave my personal cooler with you as you suggested. I'll speak with Steve at Sebring and see how the hunt went!
