I bought this bluetooth speaker from Sam's Club, $50. Waterproof and fully submersible. 20watts, 10hr battery life. Not enough to power a party, but fine for next to a fire in the backyard, and I don't have to worry about it getting rained on. Also, it is rubberized, so I don't have to worry about it getting knocked around.

In addition, I bought a 2pk of 30oz Yeti knock-off tumblers, $19.98.



And from Amazon, I got Season 1 of the Muppet Show on DVD. Was sitting around a fire w/ my son the other night, trying to think of a song to play that he would like, so I searched the Muppet Show intro on YouTube. He was amazed seeing it, and it dawned on my that he's seen a few of the movies, but never the variety show. He watched a few more clips and I ordered the dvds the next day. Surprisingly enough, it was more expensive to buy the 3 seasons in a bundle than each one separate, so I just grabbed Season 1 for $9.98 to test him out on em.
