buying horseradish

I've never been to buy horseradish.

I need it for a recipe. But I need fresh horseradish that I can grate. So I went to the store looking for it. There was a sign hanging above the vegetable bins that marked horseradish. I wasn't sure which sign went with which bin. So I picked up a couple and checked out. When the girl rang it up, she rang up yucca root. I thought maybe she had it wrong. So I came home to look up photos on the internet. Yeah, I actually bought yucca root! So now I've got to go back and find the horseradish. Hopefully I'll come home with the right thing this time.

That I'd like to see.
