Today I finished creating initial content that I wanted to have before sharing this website with broader audience (and asking them to share their places recommendations).
It was mostly manual work -- copy and pasting links from Google Maps to WordPress posts of cities. Some of them needed to be generated on a phone (website of Google Maps doesn't have the exact same features as Google Maps on iOS/Android).
I'm happy with current website look so I am not changing anything in this for now.
Added also a short how-to for those who will be interested in contributing.
I want to search through the internet to add some initial data for the cities.
If anybody wants to share some of his city favorite spots, please do!
