Bull Dog Front - Great field with great ownership
Meramac Challenge - good field but horrrible after rain
I've been to this fiel three times and absolutely loved it. The bases are great, and there are many places you can ambush opponents. There are so many things I could say about this field that are good, but everybody else has already said them so I won't bother.
The only gripes I have about Smak Zone are that Mark can be too nice, and I think it would be better if there was more cover for attacking bases. I know that would make them easier to attack, but a couple of the bases(like the bad guys base, I hate that thing, impenetrable) are extremely difficult to assault.
