Sure... crow hunting is great! Get an electronic call and an owl decoy. They will come to that like you would not believe. Stay out of sight, use light shot and be prepared to run through a lot of ammo. Not sure if there is a limit in your state but in most states, you can shoot all you can hit plus one more.

MarkJ you are seeing them congregate as they have major winter time roosting areas in the parks around your apartment and throughout downtown Minneapolis. I see the flock you are talking about almost every evening when I drive down 35. The park next to HCMC is one of their major roosts. I had to go there a bunch over the last two years and the park was full of hundreds of not thousands of crows every morning and evening. Too bad we can't hunt them in the city!
