Agree with above, deer like to see and smell, they will have a hard time doing both down in a hole. I don't see this as a good set up.
One of my most heavily traffic'd set ups was simply a small clearing in a wooded area of my lease, put the feeder down and it gets hammered every day and night until all corn is gone. Sometimes sticking to more natural setting works best, won't be as "on-guard" if it is in a more native string versus a large clearing...deer always seem to be hesitant to walk out into the open. they will go out, but they typically will sit at the edge an watch for a while, and if you make any wrong moves they are gone before you know they are there.
