v.trim

[Amy Keeley]

Yesterday I sent out a message
asking for advice about v.trim.
Scott Miller had replied that I
should check my region (thanks
for the reply Scott!).  I guess
that I should have mentioned that
the region is definitely fine.  In
fact, my map covers the continental
U.S.A.  and the only areas included
in the output "trimmed" map are 
North and South Dakota, Texas,
West Virginia, and a portion of
Virgina.  How can I successfully
get rid of my extra nodes??? Any advice
would be greatly appreciated!
