I have a TB that was picked up 4 months ago. After 3 months of no movement, I emailed the cacher and requested a status update. After 4 months I sent another email. I told them that if they were unable to move it along that I am willing to send a postage paid envelope so they could return it to me.
Anyway, I picked up a cute TB on 29 August. I emailed the owner and asked permission to keep the TB for several months while I traveled for work and pleasure. She responded with a "yes". I'm updating the TB's location and posting photographs (as was requested in the TB writeup).
