Now that Alipac has the join Alipac posters I've been putting them up all over. I carry scotch tape and a supply of posters in my car.

I've also made up my own posters which say "ICE will be patroling this area" (its not a lie cause if I ever get my way, someday they will be)

In any event I'm sure it makes the illegals uneasy and think twice about hanging around.
