Did they make the decision to go to that area independently of each other?
Yes. Had they decided to do so before arriving at the park?
Probably not. Earnest
is it possible that it was simply by chance?
No. did they follow a map of the park?
No. Was an announce made?
No. Relevant the presence of guides in the park?
No. Were visitors divided into groups and each group has a guide?
No. If so, is it usual or usually people is "free" to move?
Relevant that it was a "warm and sunny day"?
Yes! Could it have taken place while raining?
Not this exact situation, no. With any other meteorological condition?
Noish, explore. did all visitors arrive in that specific place at the same time? separately? Did they know that all visitors were assembled in that specific place?
Irr to all. Specific place...relevant which place?
Something about the location is relevant, yes. Its location inside the park? If it was near a watercourse? A mountain? A river? A forest?
Yesish. A natural attraction?
Irr to rest. little WAG...was it inaugurate a special mean of transport which conducts to a specific place in the park and all visitors wanted to try it in its first ride? So they were assembled all together in the same place somehow?
No, but good WAG!
