The visitation rates predicted in Table 1 are lower than actual rates, since they only predict the visitation observed in the sample. Adjusting this visitation for the whole sample (3000/755) yields an accu- rate per capita visitation rate. The linear demand functions estimated in Table 1 suggest that visitation would drop to zero only at distances of 328 km and 347 km, respectively, for the two regressions. At the presumed USD .15 per km, this implies a maximum price (PM) per visit of USD 49 and USD 52, respectively. Domestic vis- itation would drop off to zero only if the price per visit exceeded USD 50. Taking the integral under the linear de- mand function (VI) between the initial price P0 and the maximum price PM yields the following functional form for consumer surplus
