At the last Field Day I promised to post this Hive Inspection Record Sheet. This is just one example of something that might work for you. Please alter and edit as you see fit. It is not important that you use this particular sheet, just that you have some method of record keeping that works for you. Each time you go into a hive, you should be able to quickly review what you did and planned to do on your last visit. Keeping sheets like this in a plastic slip cover under the lid works quite well.
