Early this year, California Senator Scott Wiener began a campaign for the 'Let Our Communities Adjust Late Night Act', which proposed that each municipality within the state be given authority to choose their last call hour, possibly pushing it back to as late as 4AM.

Previously, all venues throughout the entire state were limited to a 2AM last call for alcohol services. "Nightlife matters a lot, culturally and economically, and it's time to allow local communities more flexibility," Senator Scott Wiener argued.

The Senator's efforts have paid off as his proposed 4AM nightlife bill has officially passed in the Senate, allowing it to now move to Assembly for a review and a vote before reaching the governor for final word to "allow but not require local communities to let their bars and nightclubs serve alcohol until 4AM".

This is a huge move that will affect party hotspots in the state like Los Angeles, San Diego and San Francisco if it passes through the next phase.
