Spike,

I'm with Antonio...I was a die-hard tennis player until I went to Spain for a few years. I didn't pick up a racket for two years since I couldn't seem to find a public court in any of the places I lived...I did find an overabundance of basketball and futbito courts, though. I'm sure if you're diligent in looking and asking that you'll be able to find what you're looking for. Tennis seems to be in the top five popular sports in Spain, so at least you'll be able to find a doubles partner!
