Looking at the last 10 years, it's clear that management knows how to operate the company successfully. Last year was a severe setback with hurricane and escalating fuel costs.
If you are a long-term holder, it's a decision about how well they will come back from this. Based on the last ten years, I'm holding on. I believe positive cash flow and profits will return--though higher fuel costs will likely cut into margins some if price inreases cannot be achieved.
