Things I learned, a little griping (kinda long)

I almost got hit twice today! I do not understand why these people cannot slow down for like 2 seconds to pass me at a respectable speed. Grr.

Hi Gray,
It is pretty unusual to almost get hit by cars twice in one day. If these near-misses keep happening, then it might indicate that you need to change something about how you are riding in certain situations. When I first started riding in traffic, I used to think I was doing all the right things to be super safe....later I realized that by doing some of those things I was actually putting myself into dangerous traffic situations. Now I ride a lot differently and it is rare that I find myself in a dangerous position these days.

I agree with wildhawk that if you keep getting nauseous on your bike you should get a doctor's checkup- nausea upon exertion can indeed be a symptom of heart trouble, as can 'upset stomach' pain when exercising.
I assume you don't ride on an empty stomach and are getting enough riding fuel and water?
