I wouldn't say Santa Barbara is "very close" to Port Hueneme, but its close. Thousand Oaks is much closer and has plently of caches to go around. Even for your two months in the area, you would be hard pressed to continuously cache in the Thousand Oaks and Conejo Valley area and NOT run out of caches. Lots of urban micros and cache and dash locations as well as caches that involve hikes. A park area in Thousand Oaks called Wildwood Park has about 18 caches in that park alone. You could easy nab half of those caches in 4 hours during a 6mi hike.
If you are looking for anybody to cache with, let me know. We have groups that head out all the time.
The local message board for the Conejo Valley (Thousand Oaks, Newbury Park, Westlake Village area) is located here:
