Last several evenings i've been at golf range. first time noticed light is when i hit a high ball. noticed light and it felt out of place and i felt suspicious of it. i noticed object for the two hours i was at range. it didn't move, had no sound but pulsated and got larger and smaller but, remained stationary. there are several planes and helicopters that fly in area but this is not one of them. next evening i came to range and saw same object for the hour and a half i was hitting balls. the third afternoon i came to range and it was still daylight and i purposely looked in area i was seeing the object to make sure not something there that i was perhaps missing. there is nothing but, sky. so tonight i came to range and observed same object in same area but it's never in same spot. i pointed out to friends and it freaked them out after watching it for over an hour so i decided ro report it.
