In our District for 10U all stars, the host league provides the umpires, not the district. While many host leagues provide adults with years of experience, others do not. Our league uses college students home for the summer who learned as student umpires from 7th grade through 12th grade umpiring the rec league. I don't recall an IP ever being called. Not that this is right, but this is what happens when provision for umpires is left to local discretion.
