I don't even see a current Gorham CO-OP on Xmacis, but guess there is one somewhere...lol. See 2-3 old ones that are no longer active.
But yea, what PF said is right, so much variation within town limits it's ridiculous. I live very, very close to the Winhall town line, but I'm still in Manchester. So a couple houses down would be considered "Winhall", same area as Stratton and many houses that are in the 2000-2400' range. You could have one of my nearby neighbors report 4" from Winhall (from the valley) and then have another "Winhall" up near Stratton report 20" in the same storm (theoretically under the right specific conditions )
