R.L. Crabb, cartoonist for The Union, and Virginia Brunini man a table Saturday to collect signatures for a petition to keep Empire Mine open as a state park. A California State Senate subcommittee recently voted to consider selling the park due to an annual $5 million expenditure by the Department of Parks and Recreation to operate the park. A substantial portion of that money goes for remediation efforts to eliminate toxic run-off from the mining operation last conducted more than 50 years ago. Brunini said that the effort to collect signatures for the petition will continue until April 28.
