There are a few of us around.

I'm not sure why oats just don't do it for me. I cycled around Australia for 3 months with a guy who could live on oats, and I tried for about 3 weeks, but I found I was eyeing the roadkill about an hour after breakfast. So I switched to a muesli that had nuts and dried fruit in it, and that worked. It was about twice as expensive as the oats (i.e. $2 for 750 g instead of $1 for 750 g), but still not a bad price, and I could actually ride for 2 or 3 hours before I wanted to find a fresh fruit and veg market or something.
