I sometimes read a travel blogger who loves, loves Paris and is there all the time.
Here's what she says in a recent post about Paris having its "hair in curlers":
What did I mean by “hair in curlers?” Paris is scrambling to get ready for the Olympics this summer, so there are major roadworks, and even more buildings under scaffolding than usual. (Because of the roadworks, it can take much longer to get around town by car or bus, so give yourself extra time.)
