BINOCULARS!!
I'm giving a lot of pairs of binoculars this year! My DD lives overlooking the ocean and was wishing she had a telescope but is probably moving this year so she's getting waterproof long-range bino's that will be practical in the boat. My DS has taken up hunting and needs a good pair of mid-range binoculars so he gets a chest strap as well. Then, there are the grandkids, who came in the summer and shook up our birding binoculars so they are now monocular :) so they're each getting their own pair of kid-safe binoculars.
There are still more giftee's, but I thought it was funny how so many people have ended up with the same gift for very different reasons.
