I avoid riding in heavy traffic at all cost, but if its not preventable, I don't shy away from it either. I just obey the road rules and try to get on less traffic heavy side roads as soon as possible.
I don't like it. It's not like Chicago or New York traffic but the bike lanes are few and too many drivers pay no attention to them. Riding across town or riding to either of the adjacent small towns on two lane paved roads is risky. I try to minimize the risk with bright colors and if my mirror reflects an approaching car that doesn't appear to move left a bit I'll risk a goat head puncture to get off the pavement.
