Even after all these years it still remains a thrill to go into the field and check the mongoose traps. I suspect it is the same feeling that people get from hunting and fishing. My 61-year old brother will trudge through a foot of snow on a frozen lake in northern New York pulling a sled with 50 pounds of ice fishing gear, sit on a bucket next to a hole in the ice for hours in temperatures approaching zero degrees Fahrenheit, and get excited when he catches a northern pike that he ultimately doesn't eat but gives away to his friend. The thrill has not waned for him either.
