You might want to try these Bayshore Area (Northern Monmouth County) towns, located on the Raritan Bay, that seem to have a pretty good output. I get them real good, to the south, in the northern part of Ocean County so you may be able to pull them in there.

Middletown Twp. Fire 2 FG - 154.235 - PL 151.4 (not quite as strong)
Monmouth County EMS 1 - 155.175 - PL 151.4
As for Monmouth County Fire 1, since they went to simulcasting off of the repeater towers, it doesn't seem to come in quite as strong as I did before here, but you still may be able to pick it up.
You may want to take into consideration any tall buildings in the area that may negate reception. i don't know how much of an effect, if any, they would have, but you can give them a shot.
