Here is a video I put together of a South Dakota archery elk hunt I got to tag along on and film for some good friends. Hope you guys enjoy.
2017 Black Hills Archery Elk Hunt - YouTube
I have 7 buckwheat breakfasts (2-blueberry, 2-Apple, 2 -Strawberry, 1-Banana) and 1 Chipotle Cherry Chili. All of it to your door for $35. Just was not for me.
Just as KurtR said antelope season is Sept. 30th - Oct. 15th. You can still find the deer during this time but if I were you I would either come the first week of the season or the week right before West River rifle deer season opens.
Hopefully you can find them bedded in the perfect spot. Wind is going to be your biggest challenge. What time of year are you going? Public or private ground?
