I finally found exactly what I was looking for! I hadn't played tennis for a while, but then I discovered the Tennis Insane events. Now I go almost every Sunday! Thanks so much to Jaime for organizing everything. The events are incredibly fun, you get to meet people from all over the world, and Jaime is an excellent tennis coach. He joins in the games, demonstrates every drill and challenge himself, and makes sure everyone understands what to do. The Up & Down format keeps you constantly engaged, so the two hours fly by without you even noticing. If you're looking for a fun, social, and well-organized tennis community, I couldn't recommend it more!
