Sent 2: -Poor and elderly people may soon go without legal representation in Boone County.
Sent 3: Boone County Legal Aid, which for 31 years has provided legal services to those who couldn't afford them, will close in February if a $10,000 grant from Prairie Meadows Racetrack and Casino is not awarded.
Sent 4: The legal service is one of the few programs in Iowa that offers legal representation to those who qualify without turning to the state for its services.
Sent 5: "It is a very sad situation, but that's the fact," said Alan Schroeder, city attorney and supervisor of Boone County Legal Aid.

Sent 8: If the legal service closes, he's unsure where his clients will go.
Sent 9: The city of Boone gave Schroeder $6,300 in July to resolve pending cases, said Kathy Berg, Boone's finance officer.

Sent 11: "All governments are having problems with finances," Boone Mayor George Maybee said.
Sent 12: "No one else stepped in.
Sent 13: The county didn't.
Sent 14: The state didn't."Sent 15: Donovan Olson, chairman of the county Board of Supervisors, said the board quit funding the legal service in July because it felt the county didn't need it.

Sent 17: Olson said Schroeder must prove Prairie Meadows is the primary money source for the board to grant the program any more money.
