I Love to build planes. So of course I don't think its wrong one bit. I have 2 that I haven't flown yet, and in the process of building another. As for the wife, mine is great about my hobby. So I guess I'm very lucky there. My first wife wouldn't let me buy anything unless it was "practical". Like socks and underwear. But I guess the wife I have now understands that I truly enjoy my hobby. She even told me just tonight that I should buy another plane. A foamie to use as practice so I don't crash my balsa planes. I'm still in the learning process, thats why she suggested it. As far as the weather goes Chicago sucks. Between the fall & spring, the wind hardly dies down enough. The past couple of days it was 5 degrees & thats without the wind chill. Although a couple of weeks ago it was 50 for a couple of days, but that's typical Chicago weather. Not too bad one day, and below freezing the next. Anyway, I say go for it, unless it would really upset her. As long as the bills get paid, whats the worry...
