"Normal" people go to garage sales, and the biggest one around is in the Glebe. It's fucking crazy (for example, this is at Lyon Street, a full block away from Bank Street, the main street through the Glebe, which is even insaner)
People like to share stories about the best thing they've gotten at the Great Glebe Garage Sale. The 25th anniversary of the sale is this Saturday, and in honour of the occasion I've recorded a hokey little song called "I got you in the Glebe". It's about going to the Garage Sale and finding something special. (Lovey songs, you see, are not only the hokiest, but also the easiest to write, despite the difficulty of fitting "Great Glebe Garage Sale" into a lyric. I also write songs about things I don't like.)
Despite my musical training, I'd never really properly learned to play guitar or sing, or recorded a song, or mixed one, or uploaded one. So I had to find a microphone, buy some hosting space, etc., but the half-assed result is here: Listen to and/or download "I Got You In The Glebe"
I trust you will find that the song itself, like the Glebe Garage Sale, is nevertheless great.
If you want tips on how to navigate the GGGS, I'm not going to try to duplicate David Scrimshaw's guide to the GGGS. Ottawa start apparently has one as well.
Personally, I much prefer curb shopping for free treasure on garbage night or moving days when there aren't zillions of people and vehicles. The best stuff is free, and usually harder to find.
