The tunnel is literally your entrance to everything to do with Hoofer Sailing. The most important feature of the tunnel is the marker board. This board shows wind speeds and direction, flag color (telling you who can sail), changes with lessons, racing information, and last-minute lesson cancelations. The tunnel is also the best path from the lakefront to restrooms, the shop, and boathouse. Right outside the tunnel you will find two picnic tables where almost all lessons meet (except ground school).
