Might Be A Tight Fit

Me:  You don't think Libbi can fit between the pickets of the new fence, do ya?
WTB:  How far apart are they?
Me:  Four inches apart.  I was thinking that I might have to staple hardware cloth to the bottom half of the fence.
WTB:  I don't think that she can fit through there.  That's pretty small.
Me:  Only one way to find out, I guess.
WTB:  Tell ya what, when we get the new fence put up we'll try to shove her through there.  I'll push, you pull, and then we'll know.
