Yup.

My high school (graduated last year, but I doubt it's changed since) would host a LAN party 1-2 times per year, pulling probably 2/3 of the school.

My little brother still arranges ~10-man LAN-parties, and has now managed to get the municipality to arrange smaller LAN parties weekly.

And of course, the huge ones, like Dreamhack and The Gathering are still well and alive.
