OK Roz I give in.
I agree of tack a bit just expressed surprise so many people went to Mexico. I am sure 30 years ago would be measured in hundreds.
You can get very cheap rail fares if you book a long time in advance.
Last year got a return to Birmingham from Forest Hill for about GBP 12.00.
Also return Forest Hill to Penzance only about GBP 18.00
Both booked over 4 weeks in advance .
