I can see an international trip costing money, either funded by participants or fundraiser.

Sounds like you had a cool time traveling, in the states your lucky if they have the funds to bus some kids to the public library

There were a lot of after school stuff that had travel, mainly sports and music. The foreign language dept sometimes was able to an abroad trip with like 7 students.

But the history class that wants to go to a museum can pound sand.
