I am no Lonewolf, but I do have a couple of spares around at present...
2 sets of speakers
1 extra amp
1 extra source
several sets of IC's
several sets of speaker cables
In the end, I guess I could probably set up 2 more whole systems, but for the WAF factor!
Oh well, it sure is easier to store than the old days...
2-3 sets of spare wheels
2-6 spare engines
2-7 spare frames
various exhaust, carbs, fairings, lights, and seats
Audio spares as SO much easier to store, than motorcycle spares!
