We made it out to do some exploring at around 10:30am. We were waiting for the sun to come out, but it didn't look promising!
I have to admit, we expected it to be warmer getting this far south. But, that's the problem with the southern U.S... decent weather is not guaranteed in the winter. One of the reasons we love Mexico in the winter. Once you are in that country, you can have whatever weather you want within a four hour drive.
