Where I live:
Rural southern Louisiana, in between New Orleans and the gulf.
I do a lot of recreational riding here, and most of the roads are nicely maintained with wide shoulders. There are two main roads leading out of my neighborhood, and I can do 15, 20, and 32 mile loops safely and easily. The shoulders are somewhat dirty, but as long as I'm on the shoulder, cars are not bad. I only get buzzed on roads with no shoulders.
Once you get into town, there's plenty of side roads, shoulders, and such to ride on. Not a single bike lane or path, though. I generally don't have a problem with riding on the shoulders, and using turning lanes when I need to, or cross a narrow two-lane bridge. Most people in town are okay with it, as long as you're moving and flowing with traffic, and get back on the shoulder when you get the chance. Out here in the country, though... it's their God-given right to run you off the road if they have to wait more than 3 seconds to pass. Blech. Sometimes I hate living in the country.
Where I work:
Currently, about 8 miles away from home. However, the one 4-mile road leading there is in horrible shape, has blind curves, and no shoulders at all. I've ridden it a few times, but it really makes me nervous riding it on a regular basis. If that road had a shoulder, I'd start commuting tomorrow. Since my nemesis road is before you get into town, that means if I ride it, my life is forfeit. I really want to commute to work, but there are no other roads I can take.
How I Ride:
In town, I ride VC-style, and that seems to work well. Out in the country, I ride shoulderless roads in fear of my life, so I stick to shoulders as much as possible. Nothing takes the place of knowing where you are, and where cars are around you.
