i remember back in the early 80's my uncle had a marina on lake travis (briarcliff) and this 'sinister' looking gentleman would occasionally pull his 40' cigarette type boat in for fuel... i was made aware that it was mr melvin powers as my uncle had also been from houston in the 60s. powers was an interesting looking character..about 6'3 or so well built and tanned wearing just a speedo type swimshuit with long stringy hair... he was always with a couple of very beautiful blonde stripper types.
