It's Friday. Get up to speed before the weekend with a quick look at five stories we're following:
1. Montco to respond to gay marriage lawsuit: Montgomery County Solicitor Ray McGarry will file the county's response this morning to the Corbett administration's lawsuit seeking to stop the register of wills from issuing marriage licenses to same-sex couples. The county has issued nearly 50 marriage licenses to gay couples since last week, including one to two former Philadelphia officials.
2. Dead dolphins: Experts are trying to figure out why so many dead dolphins have been washing up on Jersey Shore beaches this summer. Since July 9, 21 dolphins have washed ashore, with the latest found Thursday.
3. Judge to decide on voter ID: The fate of Pennsylvania's controversial voter-identification law is now in the hands of Commonwealth Court Judge Bernard McGinley.
