One of anything I like the look/idea of – Ti, Carbon, road, CX, MTB, whatever. Keep what I enjoy riding, sell/give-away the rest.
A big chunk of land with rolling hills, woods, open space etc and a lake with s bit of sandy/beachy shore to it and get a few diff people to come a build a variety of trails for me; someone to build some techy north shore style stuff, someone for some fun DJs and pump track, someone for some sweet flowy singletrack, someone for some hero DH tracks.
A big enviro-focused shed/chalet to hang out and have all the bikes in, etc fully decked out with everything I'd ever need.
A whole heap of coaching to get me some rAd sKillZ on the bike and to fix the bikes all back up when those skills let me down or to fettle if I don't wanna actaully ride.
Then repeat but the Ski version.
Then repeat again but the ocean/beach version.
