Posting long entries on the phone is difficult as is embedding photos, but here's one of the reasons I came to Eurocon the way I did: https://flic.kr/p/NJrRst
I'm now in Barcelona, having taken the Eurostar from London to Paris, a local RER train across Paris, then a TGV to Barcelona. I was slightly late to register today, but will take care of that in the morning.
I enjoyed the train trip, but as evening fell, I did doze off for a while. I didn't worry because Barcelona is the end of the line so I couldn't miss my stop.
I have taken a few photos, but likely won't post most of them until I get back to my computer where I can caption them.
