Rick the log book idea was not to bloat up the database. It was more like a place to put down the data in a convenient place. The database will only have the monthly average, subsequent years same months again average them to a single digit for that month. Except for the person who is inputting the data and the database operators, an average person will only end up going cross eyed reading the complete story. As to Zip codes only the US and a few others may have the luxury the rest, no.
