It might take over 15 minutes, if your being very careful and making sure you don't cut the bladder or something like that. Also about your other question about getting a guide to take you out, you might be able to maybe find a friend or something that may hunt that you could maybe tag along with. Well good luck to yah if you do decide to go out!!! Oh ya and about the smell, if you just put it aside and focus, you can sometimes forget about it.....still its stinky!
