Thanks for all the replies, I really do appreciate them.

I'll answer your questions and elaborate a little in arbitrary order.

This stretch of road is about 3.5-3.6 mi. to get to from my development to the area where the shops, restaurants, etc. are. Also, this would be almost the halfway point if I were to bike to my gym.

For me to get to that other town, this is the main road to get there. There are some areas within various neighborhoods and developments that go somewhat parallel to this road, but it'd only do about a couple miles of it.

Yes, I can wear bright colored clothes, as some of you mentioned. I can also take use my taillight that rapidly blinks red to make myself more visible to cagers.

The speed limit changes between 45 and 50 MPH, but most drivers do about 55-60 MPH.

I wouldn't necessarily use this road to commute to work on a daily basis (although I may try it in the fall when the weather cools), but on weekends to go to the gym and run errands. Also, there's a nice hike and bike trail that requires me to go this way before turning on another road. Sure, I can drive there and put the bike in the rack, but I'd like to ride the whole thing if possible.

I've only seen one biker on this road in the past 1.5 years. And that dumbass was going in the opposite direction (i.e. far left lane).

Finally, here's a quick pic I snapped w/ my phone. I can take better ones and different angles, but this pic should give you an idea of this road. As you can see, there are no sidewalks for me to bike on. Since my bike is a hybrid bike that leans towards a road bike (Trek 7.3 FX), I can't really bike on the wild grass.

Thanks again for your input.
