Stalker like

When I drive around STL city I get glimpsed of veggie gardens..... I really want to be a stalker and take some pics of them to learn what others in the area do. There is a great looking garden on Shrewsbury by the police station. I think that would go over well.
There is another on Arsenal on the way to Ares I think or its on southwest on the way to Chris's pancakes. I know i walked passed it once going to the respective restaurants. I now have a shit load of freetime at lunch now that the house is on the market and I can't go to the new home during lunch.. walking around in the heat of the day taking photos of strangers gardens seems smart right?
