Fort Worth Banners and Flags

What says TEXAS more than a flag?  Driving along the freeways, one sees gigantic American flags flying.  Not sure why BMW or Toyota dealers need to fly the large flags, but I guess they do.  This company has been in business since 1960.  Before their location was along the Trinity River but had to move.  They are now in the near Southside of Fort Worth.  This area is late to the gentrification party, but they are catching up fast.  Downtown Fort Worth is in the background.  My condo is in the whitish building with the square spires.
