don’t know where you’re planning on visitting, but if you want suggestions,
Go down to Wells area- or up to LL Bean town, and or Camden area- two nice vacation spots- BUT be prepared for gridlock traffic on the main roads- Take a boat cruise along shoreline if you can swing it- makes for a nice day out- also find out of the way lobster and clam shacks if you like good fresh seafood- if you like fishing- I believe no license is required, and you can fish the rock shorelines and snag soem real nice striped bass as they scour the shorelines, rocklines for food- a good surface plug works well-
If you go to southern Maine- stop in at Flo’s Hotdog stand- it’s world famous- she has a special sauce (kinda liek an onion sauce, but with some great ingredients) and mayo- but be prepared for massive long lines at times-

so many great places to eat in Maine- all along the coast- good fresh seafood- great steak houses- but if you wanna save a bit of money, go inland a ways- coastal prices can be pretty high-
