First, Toshi, GREAT NEWS! My dad has been fighting a cancer called "carcinoid syndrom" for a few years now, and just recently had a nice sized chunk of his liver and colon removed, and is in this experimental group, and it seems to be working, as the various little tumors are shrinking.
Now, onto my original comment when I saw a 1/72 build thread from you....."that's a little small for you, isn't it?!" Lol
I love that you are building with your grandson! Even at 2-3 years old, it is great to help develop those fine motor skills! I have started building with my son (he is turning 11 in July) after doing a group build with his cub scout pack (I am the assistant Cubmaster). He has recently crossed over to ScoutsBSA (boyscouts) so he now has fun adventures at least once a month, and merit badges that he is working on, so the model building together is really a rainy weather thing.
I suggested to him that we build two of the same kit together, so he chose Hasegawa's Osprey "egg Plane".
I submitted a photo and small blurb to FSM of our cub scout group build, and was told by Elizabeth Nash that it should be in the September issue! My scouts will be so excited!
Keep on keepin' on, my friend!
