If you could only buy 1 guidebook . . . .

[max patch]

While were on the subject.. I have the 2010 Thru hikers Handbook by 501.
It says it used to be Wingfoots guide.
It seems like a solid data guide with elevation profiles and town data.
I am kinda on the fence about whether to buy a 2011 version of a guidebook.
Whats is the major selling point for between the 2010 thru-hikers handbook and the 2011 AT guide?

Because the 2010 version was at least 3 months outdated on the date it was first issued. Its now 1 year and 3 months outdated. Get the 2011 trail handbook of your choice. We're talking about less than $1 a month for current information on your hike.
