This park needed a letterbox hybrid cache, and now it has one.
You're looking for a well camo'd plastic container containing a stamp, inkpad, logbook, and some swag. This one won't take much bush whacking, although I did quite a bit searching a good spot for it.
The stamp and inkpad are not swag and must remain in the container. There is plenty of room for small swag items and trackables though.
Timer Powers Park sits along the St. Lucie Canal and offers picnic pavilions, an equestrian arena where they hold rodeos, a playground, large open fields, a wooded area, plenty of fishing areas, and a boat ramp. It's open from 7:00 am till sunset and can get quite busy at times, so please use stealth and replace everything back as you found it. Thanks!
