Is it safe to carry my Palm Pilot with me in the truck during hot weather? Will it be OK as long as not in direct sun? I'd like to pick up more aeration on my zoysia lawns this summer. I have about 125 zoysia lawns. I send out literature with my service bulletins, but am considering doing a supplemental mailing. What do you folks think? I'm also considering some newspaper marketing this summer. Any opinions on that?
