If we put tinker toys in the category of useful toys for the younger prepper, should we not also include the "erector set" as a more useful "toy" for the serious prepper kit?
I have used parts from my erector set(s) to repair everything from bicycles to home shelving. Some of the more useful items are the larger plate elements (6" x 6") that can be used in many places. They don't need a drill to match holes and the galvanized finish prevents rust (at least in the short term).
