Hi Mark. Glad to have you here.
My story is similar, though I'm about 10 years older (will be 60 soon).
Grew up building Monogram kits, took some time off during high school and college to chase girls and then got back into it after I got married and settled into my career.
I mostly build Navy carrier aircraft, but also like cars. In recent years I've also branched off to do some wooden ship models. My biggest problem is having too many hobbies and not enough time.
Again, welcome to the forums.
Mark
