Google maps lets you send a location to your GPS now. If you click the "Send" link in the upper right-hand corner and then click the "Send to" "GPS" links you can add comments/re-name it and save it to your brand of GPS. You can click the "Send" in the balloon too.
The trick to make this work is you must enter an address or the latitude/longitude. You can get the lat/lon from maps.yahoo.com and enter them (separated by a comma) in Google.
This should work for about 99% of hunt test locations.
Here is a link to the Tri-State HRC HQ so you can see how it works.
