Ever watch a deer hide from a human? If you have there is no reason to ask this.
A friend raises Whitetails in a pen behind his home. During a visit a few years back we were standing next to the fence and could see to the other side of pen. There was some cover but not thick by any means. I could see 9 deer, some standing some bedded. He asked me how many I thought were in there. After a better look I saw 12. After I told him that, he asked if I was sure cause there were 34 deer in there.
If it can hide a mouse it can hide a rabbit. If it can hide a rabbit it can hide a deer. I saw it and became a believer.
The difference between dreamers and achievers is action.
One try is worth a thousand guesses.
