my weekly race log

What's the normal situation in the USA with road racing then? In Britain (unless it's a really major event) you're on the open road, usually on a circuit somewhere between 5 and 15 miles. The roads aren't closed to traffic, but there are marshalls (or police, in some areas) who can hold up the traffic for a minute or so as you approach junctions. So you always have to worry about oncoming traffic.

Doing this "race" this weekend, Tecate to Ensenada (Baja California, MX). It's probably going to be hot as hell at the beginning.
