When I saw this subway ad, I decided to take a quick photo of it. (I do this now and then, and it's usually awkward when someone's sitting in front of the ad.) My wife and I keep a storage unit just one local subway stop away from our place in Brooklyn. I visit our unit at least twice a year to get our air conditioner at the beginning of the summer and to put it back when the weather begins to turn cooler. We also visit our storage unit before and after traveling to pick up and drop off luggage and bags and stuff.
Is keeping a storage unit common where you live? In New York City, it's actually quite ubiquitous as apartment sizes are often short on space. I would venture to guess though that most of us who keep storage units really need to get over our hoarding tendencies and get rid of stuff that we really don't need.
Some people, however, really do need to store stuff. If you have a side gig, as this ad suggests, and need a place to store some equipment, then a storage place is a great option.
UBIQUITOUS - commonly seen
SHORT ON something - not enough of something
GET OVER something - stop doing, practicing, or thinking about something
HOARD - keep stuff, instead of getting rid of stuff you don't need
GET RID OF - throw away; eliminate
SIDE GIG - work on the side; additional work besides your full-time job
The word "gig" is usually used to talk about work that is not permanent. Actors, musicians,freelancers of all kinds use the word "gig" a lot. When a band is playing at your favorite bar, that's their gig. However, the word "gig" can also be used to refer to a permanent position when you're referring to your job in an informal manner.
A doctor, for example, might say to his friends, "I love being a doctor; it's a nice gig." However, if the doctor were making a speech at a convention, he would probably say, "I love being a doctor; it's a challenging but fulfilling profession." Some doctor's though actually do act or belong to a band on the side! If they live in New York City, there's a good chance they are keeping their equipment for their side gigs at a storage place.
