To replace the default ballpark (the one seen on field view)
1) using the iphone/pad/pod explore open the com.ootpdevelopments.iootp2011 folder
2) open iOOTP2011.app--->iOOTPData---->ballparks
3) replace the default.jpg with your favorite park. Only one park can be used. i personaly use parks from padres fan
