Sorry to say your travel bug was not in Between the Pines. You may want to report it as missing so others do not think it is in the cache. At least until it is rediscovered again.
As the Travel Bug owner, you have the ability to move your Travel Bug to an unknown location until it is found again. Visit your Travel Bug Trackable's listing on Geocaching.com and choose the option to move your Travel Bug to an unknown location. This will not affect your overall travels and distance calculation.
Cache owners also have the ability to move the Travel Bug listed on their cache page to an unknown location.
