Many factors enter into the planning of an itinerary, a time schedule, and the managing of audiences. What places to visit; whether within a given period of time allotted to the whole tour it is better to make a number of short stops at many places, or long stops at fewer places; whether a large or small audience of a particular kind is desired; whether visitors at train or truck should be encouraged to stay as long as they will or to remain only through a definite prearranged program, and then to move on in order to make room for others. All these questions must be answered before the tour begins, or better, after a brief trial trip. In some instances, special circumstances will exist that leave no room for choice in such a matter as, for example, the number of stops to be made. But ordinarily there are many decisions to make and they should be made in relation to the definite purpose of the tour. Perhaps the whole series of difficulties that arise may be summed up in two words--“don’t crowd.” As has already been suggested, the purpose itself should be simple and limited, not crowded with the attempt to achieve the impossible, so that there is no room for the definite immediate purpose to stand out boldly where it can be seen. Don’t attempt to crowd into this brief tour the information or activities that belongs in the follow-up program. The same advice extends down to the handling of audiences and every other feature. THE PLACES TO BE VISITED In considering the type of places to be visited, the two main considerations are the size of the place and whether it contains the kinds of people who may be expected to take an interest in the subject matter. Many of those who have conducted trains report that they create more interest in communities of ten thousand or less than in larger places. The larger the town the more varied and numerous are the rival attractions. In the cities the train yards are often busier than elsewhere and, therefore, the noise and confusion as well as the difficulty of handling crowds at the train is greater unless the train be stationed away from the busy yards. The towns should be selected with reference to the relation of the community to the subject matter. To take an obvious example, it would hardly be appropriate to send an agricultural train into a mining town. The whole plan of campaign may have been made in relation to one type of population, either rural or industrial, and it is rather a waste of time to try to make it serve a population of a kind that it has not been prepared for.
