Did anyone see 4 white things flying through the air during Bon Iver's set? I thought they were birds at first but as they flew more overhead they looked more like a cross. They kept flying in different formations and moved fairly quickly across the sky from west to east. I also saw them a few minutes later with a small amber light being emitted from the bottom of them.

They definitely weren't these things:

They were flying pretty high too. Just wondering if anyone else saw them besides my friends and me.

There were no drugs involved either
