Looking at the poll, it appears leaf blowers are pretty popular. I've tried it a few times myself, but as I stated earlier it takes me longer and I wind up with a dustier car when all is said and done. I can see the advantages of using a leaf blower (water out of crevices, no dripping later) but the chance of blowing something onto the car (out of the air, off the ground, out of the blower) far outweigh the good in my opinion. But since lots of folks seem to like and use a leaf blower for drying (including folks I have a lot of respect for), I would imagine it must be a pretty safe idea.
