My fave pre-season game of recent times was Inter Milan. It was a beautiful sunny day and we tore them a new one.
Also enjoyed a trip to Lincoln City a few years back. We lost 3-1 but it was a nice trip on a sunny evening and one of their fans to the right of where Villa were sitting got so much stick for being fat he had to leave. Not nice in hindsight, but extremely funny at the time. I seem to remember one of their stands was nothing more than a covered bus shelter.
I am looking forward to some cricket and a break from football, but watching Villa at a lower league ground in the sunshine is always a nice pre-curser to the new season.
