Reference visual always helps.
Big trucks not to be found on G-S Parkway, parts of NJ I’ve been, so look to other roads.
Quick map reference is that
195 and
State 18 is likeliest for deliveries.
— Sea & River Ports, Rail Junctions, and major highway junctions.
No reason vacationers wouldn’t be using, so a scanning radio would help. Festivals, car shows, fishing tournaments, etc, where large numbers need help parking.
Local drivers (bulk haulers) may deliver hundreds or even thousands of loads to a construction project over time. From a quarry or railhead.
If your setup is mobile then an earliest daytime drive might give you an idea of how well you’re receiving if you can find bulk haulers at work just prior to dawn.
Moving or changing a stationary antenna optimized for local, same thing.
Local drivers before sunrise. Locals chatting after work just past sunset.
Follow-up with descriptions a help to others getting a start.
New Jersey
in general (given thread title) it’s concentrated on the upper NJTP.
