I think aluminum has been cleared of the theory (for a few decades) that it might contribute to health issues, but I still don't use it often.
I'm in to cool for a few minutes; I've mowed about 3/4 of the front yard and decided to get a drink before I collapsed behind the mower.
I was out earlier to see what crows were up to in the street - they are bullies and attack owls and hawks. I'm pretty sure they were ganging up on an owl but I couldn't get out fast enough to see. I had to literally kick my way past Pepper at the door who wasn't letting me get it open and out. I'm going to have to put the shock collar on for a couple of days and zap her when she does that. I'm still the boss of the front door around here, even if she's the one who alerts about the mail carrier.
