You Can't Put Aluminum on a Grinder Wheel

 You can't put aluminum on a grinder wheel. I didn't do it, someone else did and now I don't want to get anywhere near the grinder because it's gunna break one of these days. I tell that story because the grind of the school year has begun. But I still like to think I'm finding the time to have a bit of fun between here and there.

I went to the Orpheum concert hall in downtown Boston and saw Mac Demarco last Sunday. It was a blast, the later half of the concert was mostly them messing around and some of the fans of strictly Mac's stuff headed out.
