I just went back and read some of the posts I missed.
Peace261- You are dead wrong about the terraine. I should know- I walk in it every weekend. Last weekend I walked in the river for 6 hours. He was walking along the road for awhile but then decided to take a short cut which means cutting across fields and in that area, you cannot cut through fields without encountering areas of groves/trees, water, swamps, man made lakes, etc. If it was a news cast you saw where they show nice flowing grass and clear spaces, that's not reality. We're not out looking in corn fields and bean fields- we're covering the entire area which includes water (river, swamps, lakes, etc), wooded areas (he may have slipped off a drop off and landed in the river ..the river is surrounded by wooded area), grasses that are about 6 feet tall, etc. So not sure what you saw but what we're searching through is not by any means easy.
I can't remember the other questions you asked so I'll leave it at that for now.
Sorry if I sound grumpy- it just gets frustrating.
Thanks!
