Hi all! Last minute packing question - what type/size of blankets do people usually use? I’m assuming if it’s 55 degrees at 9pm, the ground is still pretty cold and a blanket is recommended? We have a yeti lowlands picnic blanket, but wondering if it’s too big. 79 x 55 x 0.25 inches. We have a group of 6. I just want to make sure we are not being rude or obnoxious, and also prioritizing what to pack.
