I like the boomerang idea, & I hope it stays in circulation long enough for you to receive it again.
I love the idea of Travel bugs & Geocoins & was very excited to receive my very first tags earlier this week. After some research on the forums, I sent off #TB4JA9X & am anxiously awaiting its first log. If it manages to survive awhile without getting stolen or lost, or if it ever reaches its goal, I'll probably try to have it travel back to me. Thanks for the idea.
