Hi, I've decided to get back to tennis (started at 6, stopped training when I was 13 and played very little since then, now I'm 28 ) and, to my surprise , found out that my technique has deteriorated a lot during the last 15 years. I hoped to improve by practicing against a tennis wall but couldn't find it in my area; there are lots of courts here but none with the wall. I am wondering if anyone knows where can I find it? General tips and ideas about how to find it would also be appreciated. I'm also available if anyone is looking for a tennis partner in this area.
