Hi, the Trakable is safe! :)
My friend's dad found it in Plava Laguna, he doesn't know english and he thought it was some kid's lost treasure. He brought the "Prost!" (and a geocoin) back to Italy and showed to his daughter, who luckily remembered I'm a geocacher. Thank god he didn't took "that funny copybook with all those signatures"! So, I'm going to release it soon in a cache in Trento, Italy.
