Beginner: Phone reminds me (via vibrating) at a location

[K]

Hello, I think it's very easy but as I'm new to Automate I can't get it running on my own:

In public transport I would like my phone to remind me, when at a certain location. (so, I have a backup if I fell asleep). 

But "How" do I set it up? 

Thanks so much.

Try a flow like:

1. Flow beginning
2. Location at
3. Vibrate
4. (connect #3 OK and #2 NO to #2 IN)
