Where i worked at we would see apache helicopters frequently. 2-3 at a time. we never knew where they were coming from or why but they came from se traveling n. on the day i witness the ufo i had just left work and was traveling down hwy 565 towards hwy 146 in baytown. as i came around a small curve and could see ahead about a 1/2 mile i noticed a large upright rectangular object hovering about 120' above some power lines. the suface was a grey, dull color with no visible lights, windows or doors. it just hovered there. i took my eyes away from it for a second and when i looked back up it was gone. within a minute or two there were 2 apache helicopters flying over my location. i was working south of interstate 10 and that is where we would always see the helicopters go towards.
