this afternoon we had a biker arrive at our front door, not looking too good and holding onto his arm. He was afraid he'd broken it. We brought him in, got him sitting down, and decided he hadn't broken it, but that his elbow wasn't so good. Got him something to drink, and eventually put him on the couch, lest he faint.
He and Colin (bike in the back) went off to the ER shortly thereafter. It's now almost three hours later...no word yet.
But, yeah, we do first aid :)
