I am a nurse & was driving to work towards san fernando valley from santa clarita, ca. at intersection of the old road ( it goes along the 5 fwy) & balboa blve, as i was about to turn right (to go north) when i looked across the 5 fwy & saw a blimp-like craft above the electrical generating area & tilson sewage treatment plant. the blimp-like craft was without fond & cuppola. the thing was outligned in black & i could see through it. it was not tethered but just silently hovered. it just hivered there & there was no one on the road near me to see the vehicle. i watched it for about 4 mins (totally forgot i had my phone & could have taken pics) but made my right turn going south on balboa blvd because i had to get to work. while i was surprised at the sighting. it was not upsetting. living in los angeles & working as a nurse, i have see other unusual unexplained events. this was just another. either a ufo had problems with its cloaking device or the us gov is farther along in its stealth technology than it wants to admit. a most unusual sighting, but, hey its la.
