I'll throw the nod in for Ron Partridge and Dan Green. (John said it best--Dan is the man.)
Meanwhile, I don't know how possible it is, but how's about a simple duct tape line that officially defines where your pit area ends and where walking space begins? That might help with the issue.
Also, one thing I liked at Palmetto--either have a practice field there, or enough components of it.
And you can file this under "Extra Stuff" or whatever category you wish--how about a message board (either paper or electronic) in some semi-out-of-the-way place that teams can post their announcements/requests and et cetera?
(sorry, I was apparently spoiled by only going to Palmetto last year.
