Freelance Travel Writing

I'm considering doing some freelance travel writing for WT next year--probably in Uruguay (they're looking for South America). I don't have any writing samples yet, but I could write up a few when I visit Europe with the family, just for sampling. I could also offer to send some when I'm in Europe next month. I think it's good that I have a lot of future promise (with my education in French coming along) for travel writing, so I'll emphasize that too, I think. Right now I'm looking at LonelyPlanet, but let's see where else I could possibly apply. This is exciting. I'm seriously considering it.
