if you only have to drive in two days a week...canyon lake is pretty close to perfect...
my parents live on the water and dad did commute (he is retired now)..
on the water homes are not ridiculously priced...
as i am sure you know, the 91 sucks at all times. go in early, come home early...ortega hiway is not that bad and much more predictable than the 91...exactly one hour from cl to irvine spectrum area...
good luck
