I know that this isn't a direct answer, but I figured that the input might be worthwhile:
The Gun Club that I belong to hosts several GSB (Granite State Bowhunters) events per year. The GSB's activities are primarily south central/southeast NH concentrated. so, there are many bow-folk in the Nashua area. Contacting someone on their forum ...or just browsing it might help out. That is if you don't get enough feedback here.
