It's a natural consequence. It seems a disproportionate number of CAD students are avid fishermen. (Or in one or two cases, fisherwomen, since this class actually has a couple of girls in a rarity for the program.) But they don't fish for sport--they fish to eat what they catch. Or sell to others to eat. But they don't fish just for fun. They do have a passion and genuine enjoyment of it, but they fish for other reasons, namely, they really enjoy eating fish and are to some extent fish connoisseurs in that they think store fish is often too expensive and too cheap in quality so they like it fresh.
Like, no joke. If my instructor asked students to raise hands in regards to fishing...80-90% of them would raise their hands. Quite possibly I could be the only one not doing so. (Fishing just never really appealed to me. I'm just of the wrong generation/mindset. If you're going to fish you're going to spend a lot of time doing nothing. If you're cheating by using modern equipment, then you might as well not be fishing in the first place; if you're not cheating, then you're just doing nothing. It's just lose-lose either way for me.)
So it's really not that surprising, and I suppose in that sense, it's a good thing. Apparently fishing is a great way for people to get into business with one another, too, since a person aiming to patent a product met my instructor fishing, talked about their idea, said "now I'm looking for someone to 3-D print it" and my instructor had a glean in his eyes because in his words, "That's what I teach at the college!". This is, apparently, not an unusual occurrence, either.
I suppose the point of fishing is for stuff like that in the first place, but again, just not something I really hold interest in. I will, however, be all too happy and glad to benefit from the byproduct of this. Yum. (I mean for me fish quite literally tastes like chicken both in flavor and texture, but I mean that in a good way.)
