A quick search of the site (who knows?) did not reveal a thread of the best bunker photos....I suspect it has been tried before, but I've got some new photos and maybe you do too. :-)
I'll start here and jump in with a few more favorites soon.
I really like this beauty from Whistling Straits (and God knows there are plenty to choose from at Whistling Straits). It is way deep, an interesting shape, strategically placed and I love the sleepers.
Okay, let's see some cool pix.
