My favorite uncle had a store on 40th St a half block from Times Square for about 30 years. Before the era of Best Buy, Circuit City and in NY – Crazy Eddies he was the one of the highest volume electronics retailer in the country. He was Sony’s #1 account in teh US in the 70’s. If you had lived in The City along time you would know the store.
Its alot hotter than 65 to 75 at The Crosby. Getting to a decent supermarket will take you at least 15 to 20 minutes. You sound like a city guy. Make sure you consider that lack of convenience in your decision.
Olivenhain is the eastern portion of Encinitas and is essentially a “Poor Man’s Rancho Sante Fe”. No HOA or Mello Roos and mostly custom homes. Contrary to what you have been lead to believe there is plenty of newer product out there.
