Bachelorette Rachel Lindsay's Bev Hills Horse Date ... Urban Cowboys!

'Bachelorette' Rachel Lindsay went on a horse date in Beverly Hills of all places.

Rachel was shooting a segment of her show Thursday at Beverly Gardens Park with one of her 25 suitors. It's pretty hilarious ... check out the tudor-style mansions in the background.

It is, after all, the wild wild West in them thar hills ... and just a stone's throw from the Polo Lounge.
