Absolutely what Gail says. But, the real issue is going to be, what happens next time you run index maintenance, etc. Isn't the log just going to grow again? Then do you shrink it again? Then won't it grow again?

See where this is going?

Unless you've experienced a one time issue with the log, backups were failing or something like that, I wouldn't suggest you shrink it. It's probably the size it needs to be. If it's too big for a given drive, get a bigger drive.
