4-1/2 aint bad.. I traveled 6 hrs for a handful (25) of SMB.
Hybrid striper/white bass (Wiper-HSB) should do very well in most all of SD. I would think there is probably some growers within a couple of hours. I'll bet there are some folks here that can recommend something in your neck of the woods.
I do understand the anxiety! it's hard to hurry up and wait!! :-))
