Foot golf is super difficult. Tough to get the distance, and "putting" is pretty hard too. That course had 9 holes of this. Pretty much all in the open, and not too long. No real challenge for a disc golfer of any level, but good for families. You can also play "park golf" or whatever they call it, with plastic clubs and floorball or tennis balls. I think the hole is a pretty ingenious design. I have also seen a par 3 golf course to have disc golf and foot golf all three on the same hole. Tee is same for all, but the targets are separated. I think the challenge would be how to combine easy foot golf for families with disc golf that has any challenge.
