Tomac was certainly an influence for me, only surpassed by the late, great JMC.
I defy anyone not to watch "Dirt" and then not to go out and copy that guys riding style. Freakin awesome.
If you want to go down the XC line, apart from Tomac, David Baker and Tim Gould pretty much led the way for me.
Deb Murrell for the women as well. How coudl you not be inspired by seeing her go and win an XC race, and then ride the DH on that Formula 1 with about 0.5" of rear travel.
Aaaaahhh good days.
