This my first winter in Nelson. i currently go there for the Sroam program, and it's pretty sick.
I haven't got to experience Nelson night life to its full potential due to me not being 19 yet, but from the house parties that I've been to, and the few times I've snuck into the bars it's been pretty good. Spirit bar has some cool shows but can be expensive.
Theres a lot of restaurants you could get a job at, but retention is pretty high. I have a few friends that work at the restaurants, mainly finleys and some place on baker. They don't hate it, but getting a job in Nelson is rather hard so they tolerate it.
Now for rent, it really depends, I pay $500 a month, but live in residence. My friends pay $300 each for a 2 bedroom + loft between 4 people. Look into rosmont for some affordable living.
Overal, living in Nelson has been pretty awesome, and I'm super glad that I live here now, but i think Terrace BC might be my new home in a few years.
