Have you seen the whitish WACO Bi-plane flying around the lake? My wife and I watched it fly around the lake with the distinctive radial engine all season long and we finally made the call and took the full lake tour. What a great experience. Everyone should do it.

Anyway, my point is that ten's of thousands of people will see the parachutes and a percentage of them will tack action and try it. Go off the beaten path and your market shrinks to a core population base. I think the Laconia location is probably the best for population density for this business.
