I work for Country government, and part of my job is the interpretation and application of County ordinances and state statutes to their respective situations.
Being aware of the existence of several no-projectile ordinances in our metro area, when the time came I bought a house where I could legally shoot in my yard. I also spoke with the Sheriff before shooting there, and even had an officer come to my house and discussed it with him. I also cleared it with my neighbors, and now all is well.
I would recommend NOT breaking the law, and instead finding another way to shoot legally. You can try to get the law changed, or perhaps find an exception clause... but if you do shoot illegally, you are putting yourself in a bad situation. Any errant arrows, or angry neighbors, or accidents, or injuries may result in legal problems for you.
I had to call the Sheriff once, when a crazy ex-jailbird on drugs walked into my yard and tried to get my bow away from me while I was shooting. (That was CRAZY.) I had no problems with the officer when he showed up, and am glad I was on solid ground with respect the law.
Those laws may be unwelcome, but consider that we live in a society where in many neighborhoods there are people (mostly youths) who would cause real problems with slingshots and BB guns and bows & arrows. Those ordinances are to deal with all of that... blowgun darts and potato guns and pellet guns, etc. Sadly, when too many people refuse to exercise self-control, the only way the government can try to maintain order is to exercise its own control, and then good people lose their freedom.
