well you are in prime country between kennebunkport and biddeford pool all the wat to eagle island in saco bay is very rocky shore line and holds lots of big stripers.the bathhouse at biddeford pool is one of my personal favorites.the saco river has some good shore fishing spots and another one of my favorites is the dam at cataract falls.the breakwater at camp ellis...or hills beach and fortunes rocks...
for bait you can use just about anything alive that lives in the saco bay area,river herring ,alewives ,mackerel , eels and seaworms are among the best of the live baits, for dead bait you can use chunk mackerel,i have had moderate success with it.
once the water warms up a little they will really respond to poppers when the water is calm...i love poppers
there are lots of excellent lures as well anything that resembles any of the above mentioned live baits will work well,as well as an awesome variety of plastics on the market now.storm makes some nice stuff...as well as rapala.either way dont forget the tubes too . good luck!!
