Hey.. If you decide to go on one of the whale watching or seal watching or whatever type things... They tell you to bring a jacket. BRING ONE! I'm not sure about in the middle of summer, but the breeze over the ocean there is definately chilly.
Photo Equipment: CAMERA AND FILM!
Luggage and bags:
Just what kind of a clothes hound are you? Most restaurants are accommodating to casually dressed tourists - and that would be the only place asking for dressy clothing. Pack 1 nice size bag with slippers, docksiders and sneeks - take a sweater or jacket, and I suggest that you buy a new sweatshirt there rather than taking one with you - 3 pair of shorts and 2 pair of long pants or jeans should do it. If you need more- support the local economy and shop there - prices are reasonable if you shop. Don't forget your friend's addresses.
Clothing/Shoes/Weather Gear: In July, you could wear shorts and a light sweater or mid-weight shirt and be comfortable during the day. At night, especially if you take a cruise, slacks and a jacket are in order. If you like to sleep with the windows open, don't forget to put a blanket on the bed. You might not start out with it, but you will probably end up with it.
Toiletries and Medical Supplies: Don't forget any medications that must be ordered by your pharmacy. There is a RiteAid in the shopping center that could probably order from a prescription already registered in another of their stores - check first. There is a hospital just outside of town that can handle normal emergencies - I wasn't overly pleased with the facility, but I'm spoiled coming from a major city. Even men should get acquainted with the fanny pack. It locks around your waist and can hold all kinds of little things including a cell phone, Put a handkerchief and a bandaid or two in there.
Photo Equipment: There is plenty to see and remember - so any photo's or video taken will be cherished.
Camping/Beach/Outdoor Gear: Campers know what to pack. There are very few beaches in this area because the water is so cold. Even in July, you could use a jacket.
Miscellaneous: Plan to drive south to Freeport and go into LLBean. There are no locks on the doors because they are open 24 hours a day. There are great shops there. I usually do all of my Christmas shopping while there and then I ship it back rather than try to take it onto a plane or overstuff my car.
Go north to Camden, especially in the winter and use the tobaggen run. Last time I was there it was fifty cents a ride.
