Final Report – October 2001
Group Size
Forty-eight percent of visitors (920 of 1910) surveyed were in groups of two (Table 16,
Figure 14), which was the mode (most-often seen). The spring data set showed
comparatively more respondents in groups of 2 to 4 people, (50.8% or 539 of 1061),
than did the fall sample (44.8% or 381 of 849). Seventy-eight percent of visitors (1492 of
1910) surveyed were in groups of 4 or less. Park visitors in groups of 7 or more
accounted for 13% (264 of 1910) of overall visitation. There were also comparatively
more respondents in the fall sample who came to the Park individually, and in groups of
5 to 6 people, than in the spring sample.
