I go to the local supermarket about twice a week. Once with two panniers and once with my trailer. The latter trip allows me to pick up large items like rolls of tp or boxes of beer.
I also make trips to the health food store... usually twice a month. I normally take a single pannier.
Lately, I've been getting lazy. I'll stretch out my supermarket trip (it's less than a mile...) and discover there's nothing to eat in the house.
So I'm thinking about a trip in a few minutes. I'm out of beer
