155 mph and no cops in sight

And in fifth place, the Delta King.

And in fifth place, the Delta King.

Beware: Summer is half over! If you’ve squandered your time in climate-controlled confines, you’re running out of chances to complain about the heat before beginning the grumbles over winter’s chilly wetness. The Bridge-to-Bridge Waterfront Festival provides a chance to curse the thermometer while watching high-powered speed boats shoot across the Sacramento River. Once the testosterone of the 155-mph races wears off, visitors can drop in on the parachute artists or saunter over to the beer garden for some live music. And because this event is organized by the city of Sacramento, water-safety demonstrations will flood the boardwalk. Opening ceremonies on Saturday, July 22, and Sunday, July 23, commence at 10 a.m. in Old Sacramento; a Pajama Party rounds the night off Saturday at 9:30 p.m. on the Delta King; and an awards presentation completes the weekend’s festivities at 4:30 p.m. on Sunday.
