Thanks woogie. I shall try that.
Fuzzy, the only problem is; where I play, up in Wasilla (sorry) AK, it is really flat, so you can see movement on a good day for about half a mile, in certain spots. However, yes, you are correct. It is just that, by the time I can get to within 300 feet of my quarry, I have (usually) a direct line of sight. Therefore, if I am crunching away, they will hear me, and I will have to start all over again.
