It has a population of about 60,000. It lies in the San Bernadino valley near the I10 Interstate, about half way between LA and Palm Springs.
It has a history and some old (by American standards) houses, as it was the centre of the Navel orange-growing industry.
Unfortunately it gets a lot of the smog blown up the valley from LA, and is very hot in July and August (100F, 40C). It also has been eaten in the last few years by the LA sprawl, so house prices have rocketed, most of the orange groves have been chopped down and replaced by faceless warehouses, estates of closely packed houses, and shopping malls.
See the city newspaper web site for more information.
The real catch is that Margaret cannot work as she only has a visa as an "Accompanying Alien Spouse", and currently getting a work permit is near impossible given the current mix of illegal immigrant hype and anti-terrorist paranoia. It now typically takes six years to get a Green Card as a permanent resident alien. As a result, she is bored and homesick.
The saving grace has been the Children's Forest up the hill in the San Bernardino mountains at 7000 feet, where she has been doing voluntarary work.
