I must apologise for my poor English. In fact I was allowed to stay at the Duomo but I was not allowed to use the Gorillapod. Asked politely, btw. As I only own a relatively big Benro tripod C3570T I have never tried to smuggle it into public places, so I have never found myself in a situation where I am not allowed to get in due to the tripod. But I guess that JRP suggestion is good: there must be always a place to leave it. Regards.
