OK I think I found them. Go west on Fowler. Take a rt on USF Bull Run Dr. just past 50th street. Take a left onto Alumnni Dr and then a right on N. Maple Dr. There are 10 courts on the right a lttle ways down on N. Maple. Drive. 10am Sunday?
I can't find the public courts over at USF. I think they may be near the Sundome. I found the varsity courts but they are private. I will see what else I can find out about that.The place I play is JC HaNDLEY Park on Kings Ave. There are only 4 courts so it may be busy. Here is a site I found that seems pretty good.
I contacted Manny at Temple Terrace Tennis Center. He said they are very busy every morning. You are right. 6 clay courts. If you are a member, you can reserve times. Times are from 8-9:30 am, 9:30 am-11 am etc. He said courts start to open up around 11am but can be hit and miss. Cost is 10 per person for the hour and a half. Let me know if you want to try for around 11am or even play there later in the day or somewhere else.
I just got on here today. There didn't seem to be a lot of activity. I think the brutal summer heat may have something to do with it. I could do 10 am there though I am not sure where it is. Do you have an address for it? Have you hit with anybody from here? I am rusty but can get better quickly if I play with someone regularly.
