Fishing in my dress shoes

I have to pass by my favorite neighborhood lake when driving to Safeway, which makes it hard not to want to stop and fish the last 30 minutes of daylight. As I was returning some out of date food products I had bought, my mind began to wander over to the lake. I knew I had my light action rod, which has been ready for action in my car pretty much every day I go to work (just in case, you know?), but did I have my line clippers, a hat (its chilly), and the ziploc bag with my favorite soft plastics? I got back to the car and was delighted to find I had stashed those bass essentials in the cargo net of my trunk. But I was sans boots, I was fishing in my dress shoes straight out of work.
Sweet! I walked up to the shore just as the sun was setting and within minutes i had my first bites (which I botched two in a row, including one that yanked my drag pretty good before spitting the lure). I found a spot on a curve of the lake where there was a little school of them and worked the jerkbaits s-l-o-w-l-y. The water had gotten very cold but none the less I caught three in a row off of the same structure, then botched two more subtle bites before calling it. 3 fish, 40 minutes, not bad. I wonder how much longer I can keep catching them before the water is just too darn cold?
