BTW, the Leinie's Lodge is also well worth visiting! It's less than a half mile from the museum, and is actually the number one tourist attraction in at least a 50-mile radius.

Why so many pics? Well, for example, there are 160 kids in our high school marching band. I try to get a close-up of each student to put on the marching band photos web page. I figure every single face out there has parents and friends who would love to see a photo of that particular kid. It's all FREE, so why not?
My photos also get used in the high school yearbook, on facebook pages, for Boy Scout "Court of Honor" slide shows, etc.
I got one of the first Macs. It wasn't my first computer with a mouse; we had those at work for chip design. But those cost over $100K each. My fellow engineers couldn't believe that I got a computer at home with a mouse and windows/menus for only $2500!
It even made it into our family Christmas card photo that year:
