Something you don’t see much in Belgium are garage sales, but in the USA they are a real phenomenon. Every weekend you see signs on the streets letting you know of a garage sale nearby.
If you follow the signs, you’ll end up in the front yard of some stranger wearing a fanny pack, looking at all the things they want to sell. You can often find real gems at these garage sales but you’ll need some good haggling skills if you want to get a bargain.
In my opinion, no trip to the USA is complete without going to a garage sale!
