The last picnic blanket I ever buy?

[pastypirate]

What's the mn Best Buy? Since eating out is off the table indefinitely no pun intended.

I want a huge waterproof back ones that looks nice.

Also what is the mn verdict on those plug in cool boxes for the car?

Plug in cool boxes keep things cool to a certain number of degrees below ambient temperature. So not fridge cold, especially on a very hot day. Also unless your vehicle has a leisure battery you will end up with a flat battery if you leave it plugged i in Once your engine is off. But bung in a bag of ice and it should keep cold all day.
