For those that really want to contribute to a very worthy cause....much more than the others mentioned here then may I briefly turn your attention to the DrMaddVibe Institute of Cigarology and Drunkeness.
Now there is finally a place where you can send all of your unwanted cigars, humidors, lighters, tobacciana and homebrew making gear. Send a few, send a lot...send everything you got! It doesn't matter!
What we won't do is log on to a website for the very first time and mooch from it. No. That would be taboo. We'd leave that sort of thing to the uneducated, crass, boorish and just outworldly assholeish types. You all know them when you see them.
No, what we want to provide is a safe habitat where we can perform investigative research into subjects like:
How many cigars can you smoke in one day and still taste the flavors?
What happens when you drink 5 22 oz bottles of homebrew and try to make your own?
What brand of cigar really is the best?
Well, you keep on sending them and we'll keep on doing the research that some just never get around to.
Take care and God bless.
