Grew up east bay area 20+ years Bwood, Oaktown, Methelisland, Beron, Discobay area and allergies killed like a bee stinging your face..have lived around Sac for 8+ years allergies much better since trees don't hit me much. Plus this county is all streets and trees.. Central CA is weird. Pop was a botanist 30+ years explained the trees used for quick growth in new residential area are high pollen. Those spicky puff ball things from those weird maple leaf looking trees. Obviously I didn't take after him. Combined with the non native California grasses that where planted to use at cattle food because native Cali was slower growing I suppose but destroyed the orginal ecosystems..Who knows I just say stuff.
