I think having the alternate/pad outside, but under a covered area
is a GREAT idea !

I could do this for mine, but, the Breezeway is rather narrow, and
rain will blow in from the sides, would make the paper a mess to clean
up. BUT, still a viable option !
HA YEA !, My Male Sneakers is highly disappointed, when he can't
"greet" the Postman properly (from his point of view). He'd be pouting
for the rest of the day, if he couldn't run that guy off again. And is
teaching his little Sister Becca, just how to get that done.
(PS: The Postman nor his delivery are in any jeporady 
)
