Hi Tex!
Nice to see you here.
Glad your arrangements are going well.
As for the trip to Sevilla, I personally would leave it until the next time (and you know there will be a next time!) so that you can spend longer there and enjoy the place without rushing and missing things.
I travelled from Madrid to Sevilla via bus you know, and the driver was lovely!
But that's no reason to make the trip especially.
Oh, and when you get to Segovia please will you use your skills to work out for me how it is that the aquaduct carried sufficient water when it is such a thin affair that looks like it could only carry a trickle.
I'm looking forwards to your return to see how you find Madrid compared to Barcelona.
Have fun, and hope you meet some of those nice people in Madrid.
Jo
