CONCACAF Olympic Qualifying continues today in Mexico with Costa Rica playing its opening game against Trinidad & Tobago at 5 p.m. (vanquished 6-0 by Canada in its first game) and the U.S. playing Jamaica (which lost 5-0 to Mexico in its first game) at 7:30 p.m.

There's no television coverage, although fans can follow the Americans live at the U.S. Soccer Web site.

A preview of the U.S. game is here.

For more on the Costa Rica game we turn to guest-blogger Vanessa Rojas, a Torrance resident and Loyola Marymount University student, who qualifies to represent Costa Rica via her father, who is a native of that nation. This is her second post for 100 Percent Soccer.

I would like to start off by thanking everyone that wished me luck in this tournament.

It’s nice to have some support coming from home.

I would also like to clear up a geographical mistake that I made in my initial post. I arrived in Juarez, Mexico not Guadalajara, Mexico as previously stated (geography was never my strong suite).

Anyway, we arrived here with open arms from the people of Juarez.

There are welcome signs posted all over the city representing the different countries' flags in the tournament.

We had a police escort to our hotel as we got to view this cute little desert town that is located about 12 miles south of El Paso, Texas.

In preparation for today's game against Trinidad & Tobago we got up at 8 in the morning Thursday to have some breakfast, headed to training, lunch, then back to a last training session before our big game.

We are all excited and anxious for out first game and don’t fully know what to expect other than they are very fast and aggressive team.

Our next game is against Canada on Sunday, and that is the team that we are really excited to play against.

The winner from our pool will play the second place team from the U.S., Jamaica and Mexico pool and that is when the tournament really starts to get interesting.

On Thursday there were some little kids that wanted our autographs in the lobby and it reminded me of myself when I was their age. It made me really happy to be able to play a sport I love.

I will blog soon soon with a tournament update.

Pura Vida!
