Well we made it to Texas (through American customs which included standing in an extra line for 35 minutes because we had a banana in one of our bags! As identified by the sniffer dog.)
The trip went very smoothly, though. In particular, the boys were excellent all day. Coping very well with having too many meals and not enough sleep. Here's a picture we took while waiting for the pushcahir in Dallas:
Hopefully this makes sense - we are feeling a little tired but thought we would post before going to bed so you had something to read in the morning. We probably won't check back till midday(ish) UK time tomorrow.
