The Danbury Board of Education has voted to allow students to go on two school-sponsored study abroad trips, despite the risk from recent terrorist attacks abroad.  One of the student trips is to Paris and Spain.  Students will be traveling to Germany and Switzerland in a second trip.  The United States has extended its travel alert to Europe through February, and curfews remain in effect in Paris.  Some students have prepaid $3,000 for the trip, while others have put down a $500 deposit.
