I tried to send a message to Cave Or Die Dude (the travel bug owner) but the message bounced so I'll leave a note here.
My partner's parents are visiting Paris and are curious to get into geocaching; so I've left the travel bug with them for their trip. It might take a few weeks for them to sort themselves out and buy a GPSr but if they manage to actually find a cache in Paris it'll be worth the wait to have such a great jump :)
