I have come to love gas powered leaf blowers this past month. There really is nothing better for trail maintenance. If you have to clear a couple miles of trail a gas powered leaf blower makes it a literal walk in the park. Electric ones just don't have the kind of power that the backpack ones do and run out of battery too quickly. Or you have to rake the whole thing by hand which could take a day or two.
That being said in some areas you're not allowed to use a leaf blower (electric or gas).
