I have an idea for a cache but it may involve small amount of driving. Not far...if I calculated correctly from start to finish it totals about 5 miles. The furthest distance between any of the waypoints is about 1.5 miles, is this too far? This isn't in the wilderness it is in the burbs and if wanted one could do the whole thing walking, whole way can be accessed by sidewalks if they want. I haven't been able to find any officials rules but I haven't been able to find any multi that is like the one I have in mind. So I feel like I may be missing something.
