Green Bay Tennis Center in De Pere, Wisconsin is an indoor tennis facility that has opened its doors wide to pickleball. Play runs on tennis courts with painted pickleball lines and proper portable pickleball nets set out by staff, and the center lends paddles and balls at no charge, which makes it one of the easiest places in the area for a first timer to start. No membership is required: drop in play is ten dollars, a seven visit punch card runs forty nine dollars and never expires, and unlimited monthly play is fifty dollars. Groups can call to reserve courts, with wide open availability during weekday daytime hours and most weekends. Everything stays warm, dry, and playable through the long Wisconsin winter.
