For the RB cyclist, www.drunkcyclist.com captures the spirit of RB as well as the spirit of the true american cycling enthusiast.Its basically Porn, Riding, and Beer, in no particular order.
Ironically, Sat., the site owner was hit by a drunk driver; semi-gore pics
are up there now as well as some amusing hospital anecdotes.
The site is rich with links to different porn sites (no pop ups, really)
different biking sites,political stuff...all with a very laid back healthy dose of humor, and more than you could view in one sitting
You can literally spend hours checking out link after link of some pretty fun stuff.
His daily link dump is always fun too, although that might be delayed while he's iun hospital.
Anyway, if ever there was a site that melded the RB attitude with
the cycling community (The real one, not the one portrayed in mags)
this place is it.
Even if you're not into riding, the daily pics links are good for a quick dose of porn 
Generally, its updated blog style so it makes a fun distraction.
Enjoy (and no, I don't know the guy or have any financial interest in it)
