As much as I and other citizens of CA loathes their over reach, I'm actually in support of this because there's so many leaf blowers that run around here during the day. Most people in my bubble agree with this sentiment.

I personally have an electric blower because they're less smelly than gas blowers and easier to maintain.

I'm not too worried about landscaping pros because their existing equipment will be grandfathered into these new laws and I'm confident the market will bring equipment to pros that they'll end up preferring over gas.
