When doing public outreach the safety of the telescopes, the presenters, and the viewers is an important consideration. This is especially true for sidewalk astronomy where one is exposed to the whole spectrum of people who are on the streets after dark.
So, give careful consideration to the neighbourhood when doing sidewalk astronomy and do it with a group of presenters rather than just one or two.
Choosing a venue where there are parking attendants also makes good sense because, over and above possible inebriated street people or late night revelers, there is also the potential risk of encountering people with less than honest intentions. The use of violence by these characters to obtain money or items of value cannot be entirely excluded either.
Public outreach elsewhere is generally much easier to manage. One has either made arrangements beforehand or one has been invited to a venue. The only real problems are setting up the telescopes for the best viewing at the site and figuring out how to handle the numbers.
