My wife got those headaches when she lived over in Fullerton, then they went away when we relocated to Concord (SF East Bay). We didn’t really take much note until we went back to Anaheim to visit relatives, and the headaches returned about the second or third day we were there. Now, she knows to pack the Tylenol and expect to need a couple after 48 to 72 hours in the L.A. Basin.
Well dang....that’s right in my hood.
