 recreation. Therefore, even with the increasing mobility which 

 Americans have experienced in the last several decades, there is 

 no question but that availability of adequate water recreational 

 facilities near the local population is of incalculable benefit 

 to those local citizens. These benefits can be expected to 

 increase with the shortened workweek predicted for the future as 

 well as the increase in economic well-being projected for the 

 population with ready access to the Apalachicola estuary.
