It takes place on Beach Blvd in Hamilton, right on the border it seems where Hamilton and Burlington meet. Not only do many of the residents take part in this 2 kilometre long garage sale but people from all over come and set up their wares. Some are vendors from flea markets too. There is lots of parking on the street but you might want to get there by 8am to get a good spot. If you come from the Burlington end of the street I would drive for a few minutes to park closer to the Hamilton end of the street. Wear comfy shoes, bring some water and something to carry (or wheel) your purchases in. There is some street food available and washrooms too. (for those that might want a bit more info you can Google "Jimmy Lomax" operation Santa Claus but the info is pretty scarce) or click http://www.inform.hamilton.ca/record/HAM0870
For those of you using a GPS here is the address, 231 Beach Blvd., Hamilton, Ontario, Canada L8H 6V8
Maybe I'll see you there!
