Hahaha I like the way this kid thinks. Torches are awesome toys so I get the fascination. When you are there maybe do one of those sheet shadow plays with a torch for him, I think he would love that (unsolicited idea there, sorry).
If he acknowledges that these items date back years and are family heirlooms then he'll look after them. Gonna be so cool when you get there.
I think he'll have plenty for us to do but yeah, I think some torch games will be good. If you recall I sent him some GME UHF CB radios a while back for Christmas. I think we'll get them out and do some night-ops in the park with his dad and some torches.
This sounds like loads of fun! To be a kid again right? So cool. Enjoy it guys :)
