Is becoming a big truck driver still a good decision in this economy?

Im looking at getting into trucking. I finished a year of college, generals mainly. And the school im at offers a Class A certification. I'm just wondering about some things before i make a decision.

First of which being, the industry.
I know trucking is a huge industry, but with the economy the way it is right now, is this a good career to get into, with gas and all?

And second being, flat out, what is it like. I love going on long trips, and always thought it would be fun. But what are some of the less then obvious pros and cons?
