I never understand why there's this issue of shrinking logs - chances are that you'll need that space at some time, probably an index rebuild. The art of managing databases is to make sure you don't get autogrowths ( except under your control )

Regular log backups will help clear the content from the log. If you don't want log backups put the database into simple recovery.

As a tip you'll find the log will shrink better if you put the database into simple recovery first - but of course this will destroy your recovery but I'm assuming this probably isn't a production database.
