Here goes,
1. getting caught out in a storm, like this afternoon
2. flats, period (includes blow outs and punctures, they all bite)
3. speeding school bus drivers trying to meet the schedules the district imposes on them
4. logging trucks that drive on roads marked for no large trucks
5. newbies that post as if they knew a humorous post from a serious one, and don't.
That's about it. Riding is too much fun, and I get too much from it, to be mad or angry about it.
I could post more than two good things per gripe about bicycles and riding, I owe the fact I am mostly healthy to cycling, its just more than I want to type this late
