I'm surprised you got a call back from him. I tried for two years leaving messages on home and cell phones with not a reply. I guess lucked out not hunting with him.
With that kind of quality it sounds like a good deal. I assumed these were gentleman's hunts but more for 150-170 quality bucks. I stand corrected sir (y).
$8k won't get it done in Mexico. The good outfitters start at $10K. Alberta the same. I think $8000 for a 4 day Wyoming deer hunt is crazy but people are paying it.
