This monster thrives in raw sewage and intestines. Kehoe Lagoon seethes with 300 times the acceptable amount of this voracious creature. … Gee, you’d think the Park Service would put up a few warning signs. But, no, there are zero signs cautioning those who touch these waters that a drop can wound and kill.
