I too have had luck running and gunning without a blind. I often think we limit ourselves because we mentally think we need a blind. Archers really dont. The biggest issue is not getting them in close and drawing your bow, its being on your knees or standing up for extended periods of time. I have also had success in open prairies sneaking on them from behind. Typically the tom is at the rear following in full strut and makes for a great shield on your approach. If its really flat it is not as easy as I can make up ground quickly if there are small cuts or hills. If you busted pull back quickly, seems like slow movement is worse than moving really quickly. Also, I never really put myself in thick cover. I want to be able to draw my bow back. Its more timing than anything. You will make mistakes but its a lot more fun than sitting in a blind all day.
