Is this just a cry for everyone to tell you how good the Uni ground is?
Sammydog has hit the nail on the head, it all depends on how much traffic each ground has to cope with. I'm sure the Uni guys are made to walk around the outside of the field to put up the nets each gameday, and the fact that it gets treated like a princess is probably why it lasts so well.
I don't think there is that much of a difference between the majority of grounds between ZL3 & ZPL, change rooms however are an entire different argument... I'm all for a bit of team bonding but having to get changed with another 11-14 guys in a broom closet can get a little bit, "oops i thought that was mine i was grabbing", if you get my drift?
