He unreeled the hose from the truck to the LP tank, opened the lid and looked at the gage. He reeled in the hose and walked back to the cab of the truck. He came to the back door with a calendar for me and said "Your tanks still full." Smiling I said yeah, I know but thanks for checkin on me. We talked awhile about the weather and deer hunting and such and he said he would be back next month to check it again. I s'pose by then I might need 25 gallons or so.
