The marine VHF channels are a must being so close to the coast. Also, whenever we go on vacation, I look up what counties through which we will be traveling, and find the main PD/FD/EMS freqs for the area and often the ham repeaters. I also add things like state police and the like for interstate cruising. Not sure how much traveling you will be doing, but it's a sort of fun tradition for me to dig through the RadioReference databases, find freqs, and enter them, to see what I'll hear. Of course that could get very tedious, very quickly, depending on where you go and how often.
Also, I'm not sure what kind of radio you have, but many of the Uniden radios come with preprogrammed banks of police frequencies for the sort of thing you're describing. Most all radios also have service searches, so you can specify to search the radio's preprogrammed freqs for PD/FD/EMS etc. I find that a lot is missed that way but for unplanned trips or frequent travel that works good.
Try some of these methods, and refine them for what you want to do. The best methods are the ones you experiment with and find work best for your circumstances.
Have fun in your travels, and on RR!!!
