In addition to my interest in amateur radio, I have an odd interest in transportation systems; highways, in particular.
In other words, I'm a bit of a roadgeek.
In a past iteration of my online presence, I maintained a decent-sized website focused on that odd little hobby. However, it became a bit of a pain to maintain, and my limited free time was directed elsewhere (e.g., to chasing DX).
A couple of links with related trivia:
One of my lasting contributions to the roadgeek community was the packaging of a set of fonts closely approximating those used on highway signs: the Roadgeek 2005 Fonts (click to download).
Update: Another individual is picking up the slack. A still in-development Roadgeek 2014 series of fonts is available.
Read the license in the ZIP file for details, but essentially they're free for hobbyist use. They are NOT to be used for commercial, publication, or actual sign-making purposes.
Before you ask: I have no plans to rerelease the fonts as open source. I am not planning on any further development of the fonts. I don't even have the software to edit the files installed any more (incompatible with Windows 8, sadly).
