Does anyone know about this?
 

I came across a reference to a poem by Tolkien about the city of Bimble (?) Apparently it's a humorous bit, not too long, which he wrote after visiting that city, which he didn't seem to like very much. Can anyone tell me more about it, maybe even post it here in his/her infinite generosity ;) ?

The poem you are referring to is "Progress in Bimble Town." It was written by Tolkien in 1931 & published in the same year by 'The Oxford Magazine.' Sorry, I couldn't find it online & I don't have a copy of it, but it is a fun read - doesn't carry too much weight, but definitely a fun read.
