Here in Maine I can train my dogs any time I want to with a blank pistol on any land that is opened to the public. I can also get a permit to raise birds and shoot them at anytiome of year including Sundays.
( Sunday hunting is illegal here) It is called a propagation (sp ) permit and it allows me and my friends to shoot pen raised birds with in the location/s I discribe that I will be training in. I can also go to a game farm if they have the birds available at the time i wish to go there. Sundays are included as well.
