OAK SEASON RAMPS UP

If you’ve seen any oak trees lately, you can see many of them have dropped their leaves and are prime to start producing some serious pollen. That means you may sneeze a bit more -- and we’ll see a nice yellowish-greenish film on our patio furniture and cars. Oak season ends in May.

We’ll keep you posted if anything changes.
