Gifts for Boys ~ As soon as I figure out the right trees to use in my yard, I want a zipline! My kids (and all the neighbor kids) would be in heaven…I just know it. I love that this one, the Slackers Zipline Kit, has the seat option, making it easier and safer for the younger kids. P.S. My son just walked into the room and said, ‘Oh, those things are sweet! I want a zipline!’ So, there you go.
