Thanks for the input everybody. I have been getting around 20 feet up and it seems to be working out fine. I may go a little higher this weekend. I have had does walk right under me, but have seen no bucks. Maybe this weekend will be the time.
Here is a very handy and effective device I use to dispense corn with - but it could also be used to dispense any other seed or deer feed.
I had an old feeder that had a failed motor... I made a set of brackets to attach the feeder to the rear of the 4 wheeler - the lower one encircles the feeder and has a forward section with holes drilled in the outer ends of the bracket... these holes align with two 5/16" bolts that drilled into the rack of the 4 wheeler.
The upper bracket is an "L" shaped...
