counties) who spent >5% of their time fishing for 

 either smallmouth or largemouth bass at one of 

 the designated sites. The study area comprised 

 five sites chosen on the basis of geography, avail- 

 ability of data, and observed visitation. Two sites 

 were on the St. Lawrence River and three were 

 on eastern Lake Ontario. 



The participation equation is equivalent to an 

 ordinary demand function for a marketed com- 

 modity where quantity (visits to a site) is a func- 

 tion of prices (travel costs), income, and qualita- 

 tive characteristics. The participation equation 

 for the bass fishery was:
