Bob's dad knows all about those mud holes and it is a very dangerous situation. He walked to a rock, surrounded by water, sat for a short time and when he got up to leave, his hipboots filled with mud. It took three people and all he had to get to stable sand.
There's is a true story about the Turnagain mud flats,
south of Anchorage. Some newlyweds got mired
in the mud and a helicopter was brought in..
they tried to pull the woman out and it tore her in half. Sad but true....
