I build a little bit of everything. Can't decide if I want to build a Hanomag Half track or the Santa Maria. I have a stash of kits that I've collected over the years and having retired now might have time to build some of them.
Nice airliners, Ricardo! I used to be into 1/48 and 1/72 scale WW2 aircraft and 1/35 scale armor and military vehicles. Sometimes I'd take a break from them and do 1/24 and 1/25 scale antique and classic cars. I've still got quite a few kits, tools, and supplies but it's fallen by the wayside for metal detecting and geocaching. I used to do it in the winter when the ground was frozen, but now that time's taken up by snowmobiling and, of course, MD RESEARCH!
