We have a tradition here in the Selby household. My wife's birthday is a month and a half before mine and our anniversary is in between. We make a birthaversary event out of it. For each of our birthdays, we choose a place we want to eat and an adventure we want to go on. This year, Jen wanted to go to an awesome Greek restaurant named Amphora in Derry, NH. For her adventure, she wanted to go to Kimball Farm in Westford, MA. She's wanted to go on a hot air balloon ride for awhile, but they're incredibly expensive out here (maybe everywhere). Kimball turns out to have an "aeroballoon" ride. It's a big helium balloon tied to a passenger ring that holds twelve people. They raise it on a winch and you fly 300 feet in the air.
They also have two mini-golf courses (that were a lot of fun), batting cages, an arcade, animals, and bumper boats. You get the right idea when you hear bumper boats, bumper cars but on water. But it is SO much more fun! Take an outboard motor, put it in the center of an intertube, drop a seat over it, and go to town!
I could do this for hours! If you're ever in the area, you should definitely give it a try. It was an awesome adventure.
