can I bow hunt in September with a gopro type camera mounted on my bow?
No...you cannot attach any electronic device to your bow:
From the Big Game rules book:
In any hunt, including general any-weapon seasons and short-range hunts, it is unlawful to pursue or kill big game animals:With any electronic or tritium-powered device attached to an arrow, bolt or bow. Except disabled archery permit holders may use a non-magnifying sight with battery powered or tritium lighted reticles.
