I&#x27;m not talking about a bridge meant to stand for the ages. I did say &quot;creek&quot; after all.<p>We do all understand that there&#x27;s everything from bridges across creeks that we can literally step over to bridges across multi-mile spans of lake or ocean, right? 100 hours of civil engineering is only enough to get a sense of how big a problem the latter is, but is probably plenty to learn how to build something down in the single or low-double digit of feet range that will be safe to cross.<p>I ask this quite seriously because it seems to me a lot of people get rather black-or-white on these sorts of issues, where either we must insist that we know nothing, absolutely nothing, and how <i>dare</i> you claim otherwise in your arrogance, <i>OR</i> we went to school for at least four years and got certified and have a job in the field and their opinions are unimpeachable and perfect on this matter. Probably an artifact of too much &quot;school&quot; and not enough experience in much of anything. In reality there are very few fields where there is no way to gain a modest amount of skill with modest effort; all the ones that leap to mind block you not because of the fundamental impossibility of learning a bit of something, but because of high capital entrance fees.
