Rustic buses are old artisan modified buses used in rural Colombia and Ecuador where they are known as chivas (kid goats) or escaleras (ladders). They are used as public transport and more recently used as party buses in both countries. These are varied but characterized for being painted colorfully (usually with the yellow, blue, and red colors of the flags of Ecuador and Colombia) with local arabesques and figures. Most have a ladder to the rack on the roof which is also used for carrying people, livestock and merchandise.
