I've just heard back from Adventure South and they're happy for me to bring the trike back to NZ or to the Vietnam. And may I just say that Adventure South rock
for being so 'bent friendly.
I'm looking at the Southern Explorer
and Mekong Delta
tours. Southern Explorer would be cooler (temperature wise), greener, and probably have better roads. Mekong Delta would be more of a unique experience I think. I'm not sure which would be more fun.
So, there's a poll coming for you to chime in with which one you think would be more fun and why. :)
