Just did a metric century on my all-chrome early 80s Univega Alpina Uno on Sunday, with gugie and Andy_K, after hardly riding at all for 8 months. I had taken most of my tools out of my handlebar bar to accommodate lunch and a rain jacket, so of course I got a flat. And not having QR levers, we were lacking a 15mm wrench to remove the rear wheel. Gugie, being both more resourceful and social, was able to flag down a farmer with an adjustable wrench, thereby saving the day.
