In my own personal experience we nailed their so called schedule in our yard down to the days and times not to say that everybodies is the same way. Give or take a few hours, but we caught on to the pattern. Not to say it will not change, but for now we have it down. It has been the same pattern for the last year. There are certain days they lay the layup fat and not so on the other days. Do your homework and you will find some pretty koo and interesting things out if you haven't yet. I'm still on an everyday research of other yards in the city, but no luck with those.
