You would be surprised. I bought a new ham radio-much $$$$$-size of a large bit of hi fi, knobs, dials, big colour display the works and I was thinking where the **** can I put this so a) I can user it and b) where my wife wouldn't notice it.
In the end I just put it on my desk in full view and she never noticed it-she takes very little interest in my hobbies.
When we move house I'm officially allowed more reptiles so at that point he'll 'appear'
If she finds out in the meantime we'll cross that bridge then...
