Domo!!! Bumped into owner & great geo-friend Bigrock95 at "Pine Allee" cache in Lone Tree Hill conservation area of Belmont, MA, during a FTF attempt. Co-FTF success! Had a nice geo-chat, and was 'lucky' to be shown another part of his Travel Bug collection, including this one. During the conversation, I mentioned about the free & routable OpenStreetMaps for Garmins I always use for my Oregon 450. Garmin users go here http://garmin.openstreetmap.nl/ , and try it yourself. Seems like I might know a few tricks even Bigrock95 didn't. Good thing is, owner can now use his 550t for driving navigation as well, for cheap! Hurray! Thanks for sharing, Rocky!
