[at-l] Off AT Topic -- "i" blazes on some other trails

[hudsom at us.ibm.com (Mark Hudson)]

<<Speaking of double blazes, if you hike some USFS District's or other
Government property trails, don't be surprised to find that their trails
blazed with an "i" blaze>>

I won't embarass myself by telling you how long it took me to figure out
the blazing on the JMT. It's an "i" going south, and if you turn around and
check a northbound blaze it's a "!". (it may be vice-versa, it's been a
while).
