The things is, we've always had gators around here. (Not Florida, but in the South where I am.) If you see water, you can assume there are gators.
Recent events have shown, however, that you can't assume people know that. Many clients are adding signage.
So we're contacting other clients just to check and see if they'd like to add additional signage.
Many of them do and they appreciate the call.
Lesson: The clients don't see it as a sales call. They see it as "OMG I hadn't even thought of that" and "Yes, I need to have those signs!" It's a safety issue. It's a liability issue.
Hope this helps someone.
