I checked the cost of permits at the Rose Bowl, and it is looking like $54 per hour to reserve any of those areas.  So, if we did 2 hours of the diamond and 2 hours of the picnic area, it would be around $200. 

Should we just look into showing up somewhere sometime and seeing if we get lucky?   I know those diamonds are rarely in use on a Sunday morning around 11am.  So, we could try our luck.
