There are tons of articles and studies that classify deer as a pest. Just an example:
If you are on less than 5 acres I would be more concerned with a deer running off of your property after shooting it with a bow. Make sure you have permission from your neighbors to retrieve it.
I always thought a "weapon" was defined as something to defend life or property. A bow is a tool with a useful purpose! That's my story and sticking to it!
This is why wherever I hunt, I keep a low profile. Even on property I own! It's nobody's business to know where and when I hunt. I often park my vehicle in an inconspicuous spot and put my camouflage on in the woods. Be sneaky my friend be sneaky.
like most town ordinances the local judge will find you guilty as he determines if you broke the towns law or ordinance not whether the law was accurate or admissible. the appeal process goes to the county judge and there you can and do have a better chance with the appeal ... take some time and money but sometimes worth it... i would not talk to the person at the desk in town , I would line up my facts ask local CO for his take and get him to help with case law or what he knows and or would enforce... and i would reach direct to the solicitor of the town .... i would get his stance ... i have gone this far prior to having any problems and in some towns it worked out real well , others not so well.... a little summer ground work may turn in to a fall of big bone....
Nutley NJ even went as far as limiting what most would consider a spit ball from a straw. Anything that shoots any projectile was illegal. That being said I shot my bow for 10 years right on Bloomfield ave.
