You'll need at least one more dart! Cast, chase, cast chase, gets you a lot of exercise!  I went to an informal primitive shoot last month, and my friend, Ken Wee, offered to help me make some cane darts.  He is a former national champion.  I have at least one red osier shaft waiting to be made int a dart, and some cane that might work. When I go out to the range, I seem to spend more time explaining than casting!  The atlatl draws a lot of attention at my Hunter Education classes, too!  Btw, I think Nebraska has a spear/atlatl deer seaso.  Bob Berg of Thunderbird Atlatls has a video, and I think Ken Wee does also.  The dart rest really helps accuracy, too.
