Nice Roadgeek Page
Cameron Kaiser's "Floodgap Roadgap" is a nice page of roadgeekery, which I've just added to the links on the right. His new addition is this travelogue/photo essay of US-95 from Las Vegas down to Blythe, which also includes some detours, such as these shots of and info about the big bridge they're building to bypass Hoover Dam.(The photo is from the construction project's official webpage.)
Another nice feature on Cameron's site is his big glossary of roadgeek terms.
