Keeping a record

When we bought our present 'van ( 3 years ago now - where does the time go?) I started to keep a spreadsheet, logging the number of miles towed, our location and how many nights we spent in the 'van.  This type of record is so much easier to keep now that we have computers, but I wish I'd done it years ago.  We have towed over 4000 miles, and spent the equivalent of 6 months in our lovely Lunar!  In addition, I annotate particularly good (or bad) sites, and locations that we only pass through, but where we would like to spend some time in the future.  What I would like to know is - are there plenty more "anoraks" like me out there?
