did you find as many people as possible and make a search grid, were you on your hands and knees searching every hooftrack to it's source, looking on trees and plants it may have passed for blood? no joke, even tho this guy has a ton of money and his own large company he got his company chopper and flew around for 2 hours refueling and such untill he spotted his deer. that's dedication. you cant leave an animal that was out there to survive die just because your friend made an "iffy" shot on a deer. you dont stop just because, well, no more blood, lets go. no, get back out there buddy.
