If traffic bothers your wife, you might want to consider that a morning commute Northward on the 5 is far easier than Southward and an evening commute Southward is far easier than Northward. If you end up in Encinitas it’s going to suck for your wife getting to/from Sorrento Valley every day. If you live somewhere more Southern (PB for example) it might be easier for both of you.
Bay Park is just East of the 5 near PB with fairly easy access to the bay and bike/rollerblade/walking paths. You can also head East from there to some great restaurants and shopping in Clairemont. Bay Park has no mello roos and usually no homo asses (my argot for homeowner’s associations). Their houses range from cheap trash heaps to million-dollar, panoramic-bay-view homes.
