Beginner in Delray but willing to travel

I always loved the game and had my first lesson in September. I am 45 with bad back & knee so I would say I am 2 - 2.5.

I want to get out, hit the ball around, and get better. I need to see how my cardio and body holds up before I start playing more competitively..

My girlfriend (who was part of the lesson group) only played a few times. I would rate her a 1.0 but she is learning the fundamentals and is loving every minute. She is not as athletic as I am but she does not get tired. She is the one wanting to play every night.

Is there anyone that is also a beginner (couples or singles) who wants to hit the ball around for fun ???
