The feasibility of using ticket dispensing machines to collect campground fees was tested in the California Region of the U. S. Forest Service during the summer of 1961 and described in this report. In addition, tests were made on the performance of tickets as a source of information. This part of the research was conducted with the belief that characteristics of campers and their equipment can be estimated by analyzing the self-registration information on campground fee receipts issued by ticket vending machines. Analysis of data yielded information on place of residence, group size, camping equipment, campsite location, and duration of visit. To benefit furture campground development and design, modifications are suggested for improving response and for handling tickets. (BL)
