Not heard off the Thai twosome today. I assume they are in a Wifi / mobile blackspot. As well as Dave's UK mobile they now have a Thai sim (I think they are called tourist sims) and a new mobile number. Well I assume it's them that are texting me ! I've dropped them a text but not heard back.
If they've done the normal 50 miles today on the bikes they could have made it to east coast of Thailand and somewhere around Tha Chang but it's all just guess work. Hopefully will hear off them tomorrow and I'll update with details of where they are.
