For all who enjoy military history or those who lived through it or those whose parents did, this is a fascinating read about The River Rats and the Mike Boats they plied up and down the Mekong River of Vietnam.
I have no idea if the author is still around as his link doesn't work. I've been on them and this brought back lots and lots of memories. The Army also operated tug boats that pushed refrigerated and plain barges on the Mekong and it took just as much guts to operate them as the crews on the Mike Boats.
And yes, the navy was there with its Swift Boats, something we were always thrilled to see. (And the navy had awesome mess halls we sometime got to use. You might also check out Mekong Ambush on Amazon.com.
