It's Smarter to Travel in Groups

Wikipedia:
Flemish transport company De Lijn), usually known as simply De Lijn (literally: The Line), is a company run by the Flemish government in Belgium to provide public transportation. It runs about 3650 buses and 359 trams. De Lijn was founded in 1991 after the public transportation companies of Antwerp and Ghent fused with the Flemish part of the NMVB (Nationale Maatschappij van Buurtspoorwegen, or the National Company of Neighborhood Railways).
Socialist politician Steve Stevaert of Hasselt implemented a policy allowing some senior citizens (registered residents in Flanders aged 65+) to ride anywhere in Flanders for free. Other incentives exist for people under age 25. De Lijn is being viewed as an integral part to reduce heavily congested traffic, together with the NMBS (Belgium's rail provider).
In 2008, it transported more than 508 million passengers, for an area with a population of approximately 6.5 million.

I Couldn't resist to post these cute cartoons with more than a commercial meaning. It talks about togetherness and strenght!
