It is largely a matter of trivia, but actually the "left mel crack" is on the right and vice versa. I guess the stoners who did the fa thought that was cool... :-)
Ha ha ha, I remember hearing something about that but didn't get the joke. Oh well, I guess only a stoner would laugh. ;^) Sure is fun climbing, however.
It might be a good idea to fix the mistake on the route page unless you want to sandbag someone into trying the harder of the two cracks. Definitely a fun route.
