Spinning the helo in the second pic, you can now see the entrance is up the road and around the corner! That's quite a bit of distance to move an entrance! Those tour buses must be very loud and obnoxious! The entry road follows the curve in Bel Air Rd and eventually winds up back in the Clampett courtyard.
Finally, let's flip this helo around one more time...it appears to me that they guest entrance is too narrow for delivery trucks, etc. That's probably why this third photo shows that there are actually two entrances - the yellow guest/resident entrance and the red service entrance.
Mystery solved! But wait, what is that round structure (see green arrow)?? Let me know what you think, I'm really curious.
And now, I'll move on to another neighborhood. I promise. Unless I find another interesting tidbit about the Clampett abode.
