I remember big yards on 50x100 or 50x120 lots

with only a 800 - 1000 sqft house

and almost everyone had a garden

over half of those lots are gone in my hood now
stuffed up with 1500+ sqfoot infill on a 25x100 or 25x120 lot
no room for anything
no yard

the mobile home park up the hill has bigger yards than the infills
