Bo's again

["Larry Doub" <nftrains@n...>]

Hi Everyone,
I really like this group, there is always someone that know's the 
answers.
Can some one tell me this.
Talking with my mom, she was telling me about Bo's coming to my grand 
and great grandmother's houses for food and such.
She said that the Bo's had a way of marking houses, so other Bo's 
would know what houses they could go to to get something to eat.
My grandfather would not tell her how they marked a house and she 
does not know.
Does anyone know this one?

Larry
