This cooler which I bought for work, holds 3 3liter bottles. It is big.
It also is just big enough to hold my meds, including the spares that I had to take and the large boxes of meds for my nebulizer.
This was a very short walk from our rental cottage, after hiking through a little nature preserve thing.

Sunset over the ocean. I discovered my little ELPH camera has a low light setting and it was actually pretty dark when this was taken.
