Pretty soon my age will have a 5 handle, not looking forward to that. Spent the weekend hiking around hill country that's really kicked my azz, averaging 3-5 miles per day with 300 ft elevation change. Got back to hotel and had abdominal muscle cramps that are just terrible, even after slugging lots of water. Is this how old hunters go into retirement? The abdominal cramps are really bad, they lay you out. Is there some miracle cure to avoid this?
