[Best time to go bombing?]

I searched and everything and didn't find nothing on the best time to go bombing. Personally, I like it when very early in the morning when its still dark, and since I live up north it snows here, and when there its snowing you dont see nobody out side, especially when it gets dark. But I just want to know when do you think its best to go bombing, or at least what time at night and wat days, and etc.

[silencing cans]

What i do is just put the cans upside down, so that the ball goes to the top of the can, and it sounds very little or not at all.
