Wrong....The 150 yd rule states, you must be a 150 yds from any dwelling, outbuilding, or barn....The only provision about roads is, you can NOT shoot from or over them.
Here's the exact wording.....
3004. (a) It is unlawful for any person, other than the owner,
person in possession of the premises, or a person having the express
permission of the owner or person in possession of the premises, to
hunt or to discharge while hunting, any firearm or other deadly
weapon within 150 yards of any occupied dwelling house, residence, or
other building or any barn or other outbuilding used in connection
therewith. The 150-yard area is a "safety zone."
(b) It is unlawful for any person to intentionally discharge any
firearm or release any arrow or crossbow bolt over or across any
public road or other established way open to the public in an unsafe
and reckless manner.
