Ok i personally think that this is probably the best field for your money in san diego. You can bring your own paint and field entry is only 20 bucks. For the paint you can pick up big all at their store in poway for like $45. The rental guns aren't the best but hey it's a rental. It's not like their going to give u angels or timmy's. The novice groups are truly novice and the advanced is advanced. The games are pretty close together so theres not much waiting around. Also the fields are crazy. The woods are decent size and spread out, with decent bunker coverage. The concept/speedball, are small and the bunkers are set up so you can work good angles on the other team.
the refs are young, maybe around 15 years old if not younger. Dont bother trying to call for a paint check unless ur right next to a ref. They do keep it very safe but they a lot of times just watch the games talking on the walki-talkies. When they call 5 mins left, the game actually ends up lasting about 10 minutes so dont dump paint when you think times almost out or ull be left in the game without paint. trust me its happened to me before.
Overall its a darn good field and i play there often. Very safe, clean, and awesome fields. Im giving it a 9 though cause of the refs but dont let it deture u from going.
