Pierre pointed out to me today that in the new 2007 Welsford guidebook, Mental Floss 5.6 is rated 'R' for lead. I could have sworn it was rated 'PG' and after checking the previous book from 2001 (first cover, not the reprint with the winter nose) that it was in fact rated 'PG' there.
Which is true? I haven't led it in a year or two. I'm just wondering what has changed between printing of the two different books that warrants a R over PG?
Climb on!
