It's free, and you can top it up at your convenience.
The price rise doesn't discriminate against infrequent Subway users, it's designed to discourage people from purchasing paper tickets, which are a nuisance.
Incidentally, I think the idea that return tickets aren't available on the Smartcard is misleading - the maximum that will be taken from your card in one day is £2.70, regardless of how many journeys you make.
The Smartcard might encourage people to make more use of the system at weekends, and hopefully promote the introduction of later Sunday services.

Food bank staff
Food banks have become a necessary part of our unequal society.
I would like to pay tribute to all those who run and work for these charitable organisations.
They are needed not just at Christmas but all the year round. These peple give the time and others donate the food. It is a heartwarming exercise.
Some people would be lost without them.

David Stirling's column on the London-centred ruling clique was spot on.
How the rest of the country can continue to tolerate the patent excesses of the City, the stupidity of our politicians and the outrageous practices of the super rich is beyond belief.
Several of these MPS, lords and bankers must thank their lucky stars that they are not resident in North Korea.

It's a washout
I attempted to take the family to the George Square celebrations on Sunday. It was absolutely packed, despite torrential rain.
The kids enjoyed it - but is there any chance of a temporary cover for next year? It is Glasgow, in mid-winter, after all.
