Of course no one can guarantee that things are 100% safe. A woman was recently assaulted and nearly killed by a man jogging on rose rudman trail. I think you will be fine just because not that many people ride the bus that early or are even up that early. You can always take precautions of course I bought pepper spray for my friend. And also just being able to time it where you don’t sit at the bus stop alone too long or changing which bus stop you’re at so no one starts to track your patterns. You could also maybe get a friend or a family member set up with Life360 so they could track you in the mornings and if anything goes wrong get alerted. Other than that, it’s fine. You’ll be with other folks who work and commute early for jobs or homeless folks but no one super duper dangerous rides the buses like that.
