Ed, an 18t would get him don to 66, he would spin out.
I have 48/17 so 76.24, I thind it a good gear, works well all round and not too tricky to stop, especially not with the help of the odd herge or a bit of off roading ;)

AFAIK he said he didn't change the cog on his Fuji, which led me to believed it's 48/15 and thus a gear inches of 84.

48/18 is 70GI, not 66.

I used Sheldon's calculation, much easier with the tyres included as well;

48/17 is 74GI.

Just in case anyone was wondering, I did get there and back.

Good to hear that, was a bit worried when there weren't any noise from you.
