Seger Dog Park in Washington Square, which typically wouldn't be able to serve alcohol, hopes to host one of those happy hours. It would receive 10 percent of the proceeds from refreshment sales, probably only be a couple hundred dollars - but "then we can solicit people to become members to help support our efforts," said Andrew Freedman, Seger Dog Park board president. Running the park costs a minimum of $4,000 a year for liability insurance, wood chips, poop bags and general maintenance. Last year, with new lights installed, replaced and repaired fences and water fountain, and a fix to the drainage area, expenses ran $9,000.
