#4 well, I don't have one...
#5 no I got rid of the rest I use to have another 2 30gallon trash bags full but I gave them away and I had a dog that was sitting down and stood 4 feet tall. Still not as many as your daughter though.
#8 yep I'm a biker, but nobody said I had to been sane to be one,lol. I don't have a trike but its not totally out of the question, if my back don't start getting better or the numbness in my thighs I might have to go to one.
