Yes trades is probably the best thing ever right now, I'd rank it even higher than computer science. I don't care how high tech this world gets, we still need buildings, drywall, electrical, plumbing, etc etc... and houses and commercial buildings are going up at a crazy pace it seems. There's tons of work in trades. Not to mention old construction work like adding/fixing stuff.
If ever computer science did not work out for me, trades was always my fallback. There is actually a decent amount of money too, especially if you start your own business. I see tons of trades related trucks all the time. General contracting, electrical, plumbing, hvac, masonry etc... try calling any of em and they're all busy.
