I live way out in the country, so the only spawn point I know of to say when and where is just your typical pidgey/weedle/rattata spot across the street from my house. I know that a lot of people are having great luck in Fox Park in Laporte, though! I've been up there a couple of times and it seems like there are always active lures set. There are two pokestops in the park and one gym, but the pokemon have been great! I caught these guys there the other night!
