I lived in San Dog for 7 years and loved every minute of it. Every time I go back I ask myself why I ever left. La Jolla is nice but like a lot of the area, it's pricey. If you head just east of LJ (to the other side of I-5) you'll find University City (or U.C.), named after UCSD I suppose. This is a very nice area and may be a bit cheaper to find housing depending on what you're looking for (homes, condos, townhouses & apartments galore for sale or rent). You can easily reach anywhere in the local area from UC because major arteries (I-5, I-8 and highways 163 and 52) are all close. If you're a true mustachian you can easily bike anywhere from UC. I loved biking north by the Torrey Pines golf course along the ocean. Absolutely beautiful scenery. You can also bike south to Mission Bay Park, great for walking, jogging, picnics, etc. If you're really gutsy you can swim in the ocean from the La Jolla cove to La Jolla Shores. Lots of people do it every day but that water is cold! Bus transportation is extensive and a huge outdoor mall (UTC) is nearby with all the standard stores, food court and indoor ice skating rink. SD also has a decent trolley service serving downtown and areas south, east and north but don't believe it extends as far north as UC. Balboa Park near downtown is top notch for museums, strolling, and the world famous zoo. Lots of condos for sale downtown and tons of restaurants and bars. Good luck!
