Kind of activity . — Groups that hunted had a low rate- -only an estimated 34 percent 

 registered (based on 38 hunter groups interviewed at least once). Groups having members 

 who fished had a 75-percent rate (based on 357 fishing groups interviewed at least once) 

 Groups that neither fished nor hunted had an intermediate rate of 54 percent (based on 

 75 groups interviewed) . 



Prior use during the season. --Groups were asked if most of the people in the group 

 had visited the area during 1968, prior to the interview. More than half had visited 

 the area earlier during the season. Familiarity with the area from previous visits 

 lowered rates by only a small amount; the first-time visitor groups had an estimated 

 rate of 69 percent (201 interviews) , whereas groups that had made earlier visits had a 

 64-percent rate (269 interviews) . 



Mode of tpayel. --Horsemen registered at a lower rate than hikers--an estimated 44 

 percent for horsemen compared to 66 percent for hikers. However, the horseman sample 

 consisted of only 9 groups interviewed (against 461 hiker groups); thus, neither the 

 horseman rate nor the difference between the two rates can be estimated precisely. 



Use of outfitters or guides. — The sample of groups that used outfitters or guides 

 included only 5 groups, only one of which registered. In contrast, an estimated 68 

 percent of the groups without outfitters or guides registered. 



Time of week. — Weekday registration rates were estimated at 72 percent (157 inter- 

 views). Weekend and holiday rates were lower, 62 percent (313 interviews). 



Reasons for Not Registering 



About 32 percent^ of the 470 groups who were interviewed did not register. These 

 groups were asked by interviewers why they had not registered to try to learn if there 

 is some way to raise registration rates. A tabulation of their replies follows: 



Reasons for failing to register Nonregistrants 



(percent) 



In a hurry, did not want to take time 21 



Planned to register on way out 12 



Had registered on a previous visit, thought 



once per season was all that was required 8 



Only going a short distance, did not think 



it necessary to register 6 



Did not notice registration box and sign; 



in some cases because of darkness 5 



Did not like to register 4 



Said they had registered, but had not 4 



Raining 2 



Thought someone else in party had registered 2 



Miscellaneous reasons 28 



No reason given 8 



^Proportion of interviewed people who registered (68 percent) is higher than the 

 estimated overall registration rate (65 percent) because the latter is a weighted 

 average. Rates were below average in some lightly sampled strata and high in some 

 heavily sampled strata, accounting for the. discrepancy between raw and weighted figures.
