There is no traffic that you’ve seen right now, but you’ve done not been looking for like two minutes early in the morning. Some might come along later.
There isn’t much good cover around the gates, the closest the terrain provides good cover is 400ft away, past that point it’s kind of an open plain path without much of anything to hide behind. The gates have physical doors made of wood to bar entrance, but they’re fairly light and seem to prioritise being easily opened and closed over being massively secure.
Also sorry for taking so long to reply, I didn’t think to check for edits and so missed the questions.
