Ohio Delorme Challenge
The Ohio Delorme geocache requires a visit to each cache in the Delorme atlas for Ohio but only visits after the cache was placed will count towards the cache find. Once a cache has been found on each page you then get the co-ordinates for the final cache hidden somewhere in Ohio.
With the aid of a KML file, the recent finds pocket query, GSAK and Google earth it is quite easy to work out which pages you need to do.
First download the Ohio Delorme KML file from the main cache page, GCZ554. Next download Google Earth (if you don't already have it already. Finally you want a .loc file of all your finds since the 2nd of December 2006 when the cache was placed. The easiest way to do this is to download your latest finds into GSAK, then using the filters set State=Ohio, Found=Yes, Date=On or After 12/2/2006. I saved the filter as Delorme so I can run this whenever I need to check my status.
In Google earth open the KML file and then open the loc file to see the caches appear in gridlines for each page. You may want to turn off extra options and layers such as road names, community uploaded content etc. This will give you a cleaner picture. 
The picture above shows the gridlines and the picture below shows my found caches so far. I've actually found quite a few other pages but unfortunately they were before the cache was placed so they don't count.
So far I've found pages 45-48,55-59,65 and 67-69
Meanwhile TeamJNLe4 completed all the pages yesterday and now just has to go for the final cache - congrats Jonathan!

New Mapping Software to geotag pictures
WWMX is the current software that I use to geotag my photo's and I'm always on the lookout for some better software that will do the trick. Today I came across locr which seems really nice. The interface is cleaner and looks much better and also integrates with Google Earth and if you use locr then it also integrates with that website - It's actually their bulk uploader tool.
However if you have a garmin gps you may find that loading in the waypoints does not work correctly so here are the complete steps for encoding your photos.
First download the locr program to your pc - you will also need .net framework 2 on the pc (which it will download and install if you don't already have it)
Use mapsource to obtain the tracks from your gps and save the data as a gpx file.
If you have GSAK then you are in luck and can convert the gpx file to an nmea file otherwise download and install gpsbabel
Use the following command line to convert your gpx file to nmea format - replace the paths to your gsak (or gpsbabel) location as appropriate
C:\Program Files\GSAK7\gpsbabel -i gpx -f data.gpx -x track,fix=3d -o nmea -F output.nmea
If you save the following as a .bat file and create a shortcut on your desktop you can then just drag your gpx to the shortcut and it will create you the nmea for you in the same location and with the same name (but with the .nmea extension)
"C:\Program Files\GSAK7\gpsbabel" -i gpx -f "%1" -x track,fix=3d -o nmea -F "%1.nmea"
Once the file has been converted you can then proceed to geotag the photos.
Open the locr program.
Add the photos that you want to geotag.
Open the nmea file. As soon as the nmea file is opened, the photos will have their locations updated. However the files will not be stamped (and there will not be an x in the flag column).
Click the Automatic geotagging to set the flag status to x.
Your photos will now be geotagged.
You can test this by removing the files and tracks, and then loading in the picture by itself. At this point the picture will be tagged and displayed on the map.

Cache planning along a route in Autoroute
If you export your gsak caches into Streets & Trips/Autoroute, create a route and then use the Show or Hide places option you can get a list of caches along your trip. I've made a rough tutorial online
