I'm in Goodyear as well but for more than a couple weeks. Here's the run down, Fightertown is closest and has a great rec-ball layout. FAP is next in distance, it's got turf fields, self filling stations, and seems to cater to primarily players who are practicing for tournaments but do also have a couple rec-ball fields. Next would be Cowtown, It's the only place in AZ that has actual grass airball fields, and also a great rec-ball layout that's huge. All three have friendly staff, it's gonna boil down to what you have a flavor for when you wake up the morning you plan to play.
Everyone I know is in one of two categories,
1. Your either too important to lose by lying to you, or 2. I don't really care about your feelings enough to care what you think so I won't lie to you.....Either way you get the truth.
