We coveted those MRC gatefold catalogs like gold back in the day! They changed from time to time, so we traded them to be sure we had them all. Lying in the grass during recess, we would dream of our next kit.
I think my dad let me use the gas mower when I turned 13 or so. $3.50 per week to help dad in the yard on the weekends, collect the trash and wash the dishes throughout the week. It made every penny count, and took me at least 3 weeks or more to save up for a Tamiya kit. But it made the getting sooooo much more satisfying, even though the kits I built turned into mostly turds.
