Have there been car break-ins in the park this past year? (I know several places in the city that have had an issue with this, but hoping not here!)

I was enjoying the beach from sunset until almost midnight. No problems

There have been some but it's seems less than better known parks.

I would expect a lot of break ins because all parks are very secluded. However if you don’t make it obvious that you have expensive stuff, the chance for a break in goes down drastically.
