I fall into a whole other category - lets call it selective acquisition.
I don't have a whole heap of bikes and probably never will. I do have a variety of select toys & projects though.
I have my ZX10R road bike that I got new & will never part with. I work on it myself, and take great pride in my immaculate 40,000km bike. At some point I will acquire an identical model to build as a track bike.
I've always wanted a late 80s CR250 and for a few years have wanted to do a reno, two birds one stone. I pick up an 87 CR250 tomorrow, will restore it and I will keep it for ever and don't see the need for any more bikes.
I have my guitars, each with a specific purpose; The thrasher, the soloist and the project which I have customized to the Nth degree to explore the nuance of tonal variety . I have a Marshall amp and customized pedal box. I don't need any more.
I have my compound bow & accessories - just one and that will suffice.
As my forum name suggests I have a decent SLR camera and lenses. My old profession is still a hobby, but I don't see the need for a house full of gear, just what I need/use.
With a variety of interests I am kept occupied and everything has it's use. No wastage, no need to compromise cost due to other projects or worry of over investing and nothing gathers dust - I have what I like/need/use and I enjoy my life immensely. You could say I'm not entirely immersed in a particular scene, but variety is the spice of life and hopefully I'll never get bored or lose interest in any of them.
