Did you, after some sick sends, of high lines or your latest trad proj, then partying away the evening, grab a blue and white cooler with ~$40 in groceries/beer Sunday (Sep 11) night. I think it was probably someone with the large group of high-liners with whom I partially shared a table that night. My assumption is that you mistakenly grabbed on the way out.
If this is you and you got home to find a bunch of free groceries in a cooler that is not yours, I'd love it if you could reach out to me so we could figure something out. No harm no foul.
