Our friend Snoggeramus in Australia, who's sent a lot of good material to us, dares us to watch this video clip of El Camino del Rey in full-screen mode. I tried, and found it really hard! Talk about vertigo . . .
Remind me not to drink anything alcoholic before tackling that . . . in fact, remind me not to tackle it at all!!! However, if you're more adventurous than I am and would like to know more about it, there's a long article here about crossing El Camino del Rey.
