[dovetails]

Hi guys, I tryed the find a sawyer thing,and only 2 mills listed in NH??
Anyhow, my sister lives way up north,as in can walk to canada in 10 mins.
She has some big pines their gonna be taking down this summer,and is looking
for some one to cut into 2x" and boards. I go up there in july for a visit, but ain't gonna haul the mill with me on vacation! I live in N.C.  Any one portable in upstate NH?  I believe where the trees are is in Colebrook,N.H.
