ポン菓子やってるのを見るとついつい懐かしくて買ってしまう

10年以上まえに不思議な後輩に声かけていただきやっていたことがあるからでしょうか、

短期間ですが軽のハコバンにプロパンやらコンロやらポンのマシーンやら乗せて小学校の前とか　商店街とか　公園の横とか　スーパーの横とかでポンポンやってたときありました。

懐かしい

Anytime I find good old pop rice made and sold on street, I just cannot resist buying a bag.
It’s maybe because I once made and sold puffed rice by myself more than 10 years ago, as one of my younger friends invited me to do it. 
It was only for a short while, but I got a small van stuffed with a gas tank, cooker, pop machine and so on, and I would bang loudly in front of an elementary school, on a shopping street, by a park or a supermarket.
That takes me back.
