I belong to a group thru Yahoo which recycles things. You can check it out at:
http://www.freecycle.org/ I have given away so far, 3 tv's, games, the extra laminated wood I had; and once, just about a mile away, I picked up about 100 empty DVD boxes for my niece who makes her own movies. Someone would absolutely be thrilled with your 70's appliances. Only thing is you will get quite a few emails, but you can digest them. That is what I do. I think this is a great service also, because it lessens the load on the already overfilled landfills. It has to be free, but, think also, how nice it is to give to someone who maybe, needs it to be.
