Take the following as truth: Even if you can't be in Puri for the tremendous Rath Yatra Festival in June/July, the town is worth a visit just to see a community devoted almost entirely to the industry of its great Temple of Jaggannath, either directly or by trading with the pilgrims.
Then the following statement: "People take off school and work for the Rath Yatra festival." is true, false, or inconclusive?
