Skirmish - Poco has less fields, although most are just as good, is just as expensive as Skirmish, and there's less of a drive to Poco from Philly, and MUCH less walking on the field.
Cobra Command - Poco beats Cobra in every respect but price.
Fireball Mountain - Poco has 1 or 2 more fields, field quality is about equal, Poco's reffing is MUCH better; too much cheating and bad reffing at Fireball. This may have changed recently, though - I understand Fireball's refs have gotten better.
I've been playing at Poco for quite a while, although I don't play there as much as I used to. I've reffed there as well as at other fields; however, I don't ref any more. The fields are good, and are getting better because Poco is putting money back into the field unlike many other fields (otherwise I'd be bored with them by now). It's the only field in the tri-state Philly area that has anywhere near the field quality of Skirmish. Poco also puts a huge emphasis on safety; I've played on a LOT of East Coast fields, and Poco is in the top 3 for safety. They don't allow screwing around in the dead zones, are always telling people to put bags on their barrels and whistle games dead if a mask is pulled. They've got a store onsite that has every basic item you need. It's a great field for newbies, corporate events, bachelor parties and weeked warriors.
That being said, experienced and tournament players won't be happy with only 1 speedball field, no walk-on paint and the fact that there are kids and newbs in most groups.
Poco's not perfect, but the complaints of some of the other reviewers are exaggerated. Frankly, the negative comments seem like sour grapes or whining. The refs don't allow cheating, and there is NO 'house team' whatsoever. Refs do wipe splatter from newbies to prevent confusion. There is FAR less walking than at Skirmish, and the prices at Poco and Skirmish are IDENTICAL (I just checked both web sites), and if you are anywhere near the Philly area the drive to Skirmish is an hour or more longer.
The pricing is what gets most people. Just like Skirmish, it's $99 a case for field paint. Field paint is almost always Team Colors. However, you can buy a membership that brings the price down to $65 a case. If you play 4 times or more a year, you make your membership fee back, and then some.
A couple of people complained about the refs being 'too talkative' and then said they 'weren't approachable.' MAKE UP YOUR MINDS ALREADY! Do you want them to talk to you or not? The refs are used to talking because they are used to newbs and kids. I know several talk too much smack, but so what? Get in there and play and quit whining!
Personally, I prefer fields that let you buy your own paint (Marbs!) and have more experienced players on the field. However, in the Philly area, if you want to play woodsball, Poco's the best there is. Just buy the doggone membership! If you want tournament play, a lot of speedball, or no refs looking over your shoulder, go somewhere else. I've heard Dell Hobbies in New Jersey is great for speedball and runs a pretty tight ship.
I give Poco Loc an 8; I subtracted points for pricing and for too many newbs/kids.
