I usually go down the center and then push snow to each side from there.
this. and i prefer to shovel a couple times, and just do a couple inches at a time, vs. waiting until the storm is over and having to do everything at once; my back likes it more too. plus by then, youve probably driven over it or walked around on it, and packed it all down, thus packing it down and making it harder to shovel. however, i need to remember to clean the cars off before i shovel, cause i always end up clearing the driveway, then cleaning the cars off onto the cleared driveway, then having to shovel again.
shovel wise, i prefer the scoop ones with a straight handle. we tried the bent handled ones a few years back and I personally didnt like them.
