It's hard to say what the weather will be doing that time of year but if you are anywhere north of Duluth,MN. i can almost guarantee it will get very COLD in the last hour or two of the day before sundown.You will need to practice with alot of heavy clothing on to prepare for the realistic hunting situation.People will think you've lost your mind practicing with all those clothes on in Nevada!That probably will be a little early in the season for the deer to being really active but i know they have BIG deer up there.Good luck!
