There are currently 5 White Jeeps that I've found listed in caches in Washington State. They are all in the mountains and only one is reachable by driving (with an SUV most likely). The rest are at least 6 mile hikes round trip!
If you go to the Track Travel Bugs page and click on Advanced Search you can find all the logs for the Jeeps. I searched for "White Jeep" and came up with 5,015 travel bugs - the 5,000 from Jeep and 15 wannabes. I then scanned through them and found quite a few that had no miles logged on them yet and were still in the hands of the same user for at least a month or more! I e-mailed one of them and asked them if they were going to do what the Jeep's goals said (in the log they said they would move it along soon). They had over 2,500 finds and in their profile had the nerve to ask anyone if they wanted to "trade" Jeeps with them (they had 5). Can you believe this? A veteran cacher like that ought to set an example.
It wouldn't take too many of us to pick a letter of the alphabet, find the White Jeeps that have been stagnating, and send a polite reminder to the current holder to move it along for others to enjoy. I'd be willing to help, for now it looks like I'm going hiking if I want another one....
