Attn: Pickleballers. Calling all self-proclaimed pros, amateurs, rookies, whatever. If you pickleball (yes, it’s a verb now), this place is a must. Preston Playhouse (a hop and a skip north of I-635 on Preston Road) is a pickleballer’s dream. And the place is brand new. With nine indoor pickleball courts, two indoor padel courts (more on padel in a second) and a heated indoor swimming pool, Preston Playhouse claims to be the largest facility of its kind in Dallas-Fort Worth.
