As far as writing letters, everyone needs to write their elected representatives a certified letter. It requires a signature. If everyone would do this, it would bombard their office with tons of mail that requires signature. This would cause some attention as well.
Of course a transportation workers strike that would shut down the national transportation system would definately get attention. However, not everyone would get on board to do that.
