It's been just shy of 13 years for me, and it's been a great ride. Lots of great folks here and lots of fantastic information.
When I look back on it all I realize it's also been 22 years since I started building my home layout, and somehow even with the input from OGR in those days, I managed to get most things right. There are certainly a few things I would do differently today of course, but hey we live and we learn. (Hopefully)
