I heard from the dermatologist today. The spot on my back is a keratosis, which is not a skin cancer. It can, however, turn into one. Current plan to have it checked in about six weeks. We'll see then if it's wiser to remove it or keep watching it.
I'm geting sucked into the school fundraising machine. I am a big fan of passive fundraisers, and am working to activate more of them for our school. I hate asking folks for money and I don't like being asked, so I strongly prefer fundraisers that ask only that I click a link before shopping online or clip a box-top.
