the Newport Beach Cougar flourishes about 10 miles south of HB. They can be found in any number of local watering holes, filled with collogen, botox, and all manor of synthetic beauty enhancements. Do not engage a NBC by staring at either their abnormally large silicone enhancements or directly in their eyes. It also helps to have a drink in both hands so as to give the impression that you are with someone else

As a transplant from Chicago, I would say HB is definitely a place for a younger crowd to have fun, but housing can get even more expensive there (I live in Lake Forest, about 15 miles south). It is a beach city, so it is a bit dirtier than the inland cities, has a larger population of homeless - but then again, it IS “Surf City” as dubbed by the Beach Boys 
You may want to check into a job before you get here, things are bad and getting worse. While the surf industry is based here (a couple surf companies right off the 405 in Irvine), as others have mentioned, unemployment is over 10%, taxes are going up, and I have already heard of small companies leaving, and some large companies looking for alternative locations.
On the positive note - now is probably the best time to purchase a home here if you already have a job (and it is stable), and you have the money. I believe my home value has dropped 40% from about 2 years ago, so even though we have equity, you won’t see us selling any time soon. My neighbor is a foreclosure attorney and said he still expects it to get worse through next year.
Training - it IS great. The nice thing about HB is you have all sorts of options for your training. Head north or inland along the river trail - it is pancake flat. Heading south, and even further inland (Santiago Canyon), you have hills, and even mountains that you can climb to your heart’s content (I used to do a 20 mile loop in Laguna Beach south of HB, and I had 8 climbs of over 800 feet in that loop - usually between a 6-12% grade). You can swim in various locations, there are always group rides out of most bike shops (although you don’t need to find one - if you ride along PCH in HB at about 7:30am on Sat. morning - the groups will just find you 
So, come on down if you can make it work financially. We can always use less self centered folk from other parts of the country
