Since the weather is getting nicer, the courts fill up faster. To compensate, I've moved up the start time to 9:00 AM. I don't expect that everyone will want to get there that early so if you can't make it until later, that's perfectly fine. We usually play from 9:30 - 12:30 (sometimes even later). You can show up anytime.
I know Saturday doesn't work for everyone. Let me know what does by heading over to the Poll's page (More > Polls) and filling out the "When does Tennis fit in your schedule?" form.
