Narrative:

Approximately 1 mile east of tsp (right off the departure end of runway 11) I had an uncomfortably close encounter with a glider doing loops topping out at about 1;500 AGL. They came up and were upside down at my altitude approximately 300 feet away at my 10-11 o clock; pointed towards me. I made a turn away from the glider (though it probably wouldn't have hit me if I hadn't).before takeoff; I remember hearing a tow plane announce a glider release at 9;800 [feet] northeast of the airport which I believe was the same plane; though I don't remember a distance. It made no position reports after that and I don't remember any responses by it to other aircraft in the pattern.this is the second relatively close encounter I've had with gliders in the tehachapi valley and one of many times I've been uncomfortable with glider operations in the area (including several right near the traffic pattern at tsp). There is a glider port; L94; about 3 miles southeast of tsp which has a fleet of rental gliders with no radios and no transponders. The tow planes will occasionally report release points on CTAF (shared between the two airports); but after that; there's nothing other pilots can do apart from keeping eyes out for them. Furthermore; with no radar coverage in the tehachapi valley; bakersfield and joshua approach controllers will drop flight following well outside of tsp. This leads to a tight valley with traffic at two separate airports generally not talking to each other and occasionally infringing on the other airport's patterns - it seems like a recipe for a midair.
