At the local beaches, pay particular attention to the safety
of your belongings. Most beaches in the area are staffed with life guards,
but you should always take responsibility for your own safety in the ocean,
and watch children closely. This is Sunny California, so remember to use
sunscreen or a beach umbrella to avoid burns.
Traffic and safety: Local highways and interstates are
typically very busy and very crowded. Fast-driving residents mixed with
tourist drivers reading maps while driving on unfamiliar highways is a recipe
for an accident. If you are planning on driving in the area, be sure to
study your maps and plan your routes beforehand, as you will need to be
very attentive to keep up with the pace of the busy highways. Be sure to
allow plenty of extra time for traffic delays and avoid becoming a victim
of road rage. Do not be surprised if you come across a low-speed car chase,
as they are not all that uncommon.
