Well, I hope this doesn't sound too silly - but I'm in the RC(radio control) hobby... which are hobbygrade RC's.
I am making a rock crawler, and Sam always kept me company when I started the build(a little over a month ago)... always used to pet him when I was figuring stuff out, etc
I got the idea of dedicating the crawler to my cat - he was always there for me and I want to remember all of the good loving times I had with him.... even if that did mean him biting at my boxes!!!LOL
