Not sure exactly how much Tillie is in Blackhawk in Madison, but I have spoke highly of this fun, short, sporty (call it what you will) layout. Tons of interesting shots, lightening fast, smallish greens to really make you question your approach shots and strategy on playing each hole.
I for one really enjoy the place, but you are correct that it gets very little "press" or praise compared to many of the bigger name courses in the area.
