True. All the more reason to be a friendly approachable person at the track! Friends will lend wheels (cogs, chainrings, tools, etc.) to friends in need, I find. And really, I've had a tubie blow exactly once in more than 10 years of track racing (touch wood), so I don't feel the advantages of a quick-changing clincher really outweigh the safety benefits of tubulars.
But clinchers work too.
