While some people love Vancouver Island, I could not take it at all. I lived in Victoria for 4 years and have to say that for a lot of the time I was even cold in the summer. I missed my idea of a hot summer so badly. I hate haivng to bring a jacket and raincoat with me even in the summer. I don't like grey skies and rain, or drizzle, and that seemed to be what it was like there much of the time (the pouring rain usually starts on Oct. 1st and stays for like what seems forever).
Nanaimo's weather is supposed to be a lttle better, or little worse, than Victoria depending on who you talk to. It used to have a very bad name but I think it's improving (or at least trying to).
I would not put much merit in the poster above who mentioned about the KKK, his post just doesn't make sense to me.
I nyself like the Okanagan the best but it's not a thriving metropolis that's for sure, but then again, to me, neither was Victoria (but I'm from a big city). Victoria is the closest thing to vibrant of the 3 though.
One thing I found about living on the island is that while it's pretty easy to get off it, the cost is great if you go by car. You're looking at $100 return (at least) and long waits for ferries etc. and if you go to the US you can add more time for customs. When a ferry breaks you can have a 4 sailing wait (that's fun
, been there, done that!). To me it was not something to do for the day as it would take much of the day getting off and then back on again and you'd have no time at your destination. I only left the island for longer trips or to catch a plane out of Vancouver but at times I so wished I could just get in my car and take off (I know you can but I mean off the island with no planning).
That's another thing, it is more expensive and inconvenient to fly off the island.
Good luck!
