Hello! Just thought I'd let you know. I hunted the Martin, SD area last year and it was not good at all. The reason I went there was because of all the walk in areas. Once I got there I noticed those areas had no cover at all. They were mostly picked wheat fields. After one day of hunting I packed up and headed towards Redfield, SD. Maybe things have changed since last year. Something to think about before you drive all that way. I drove 11 hours from Minneapolis and was very disapointed. Hope this helps.
Yes I hunted the refuge. Lots of hunting pressure not only from the pheasant hunters but also deer hunters. I only found one walk in area that had good cover. In that spot I flushed some sharp tail grouse and bagged one.
