Bret and Brian were unstoppable forces in bmx. Richie Anderson was the winningest ametuer rider ever. This family run business made some great bikes.
Instead of breaking it up (in the drop down) 78-80, 81-83 and 83-85, maybe it should be 78-82 and 83-85.

GT took over (started building) Patterson in 83 and the frame design/dropouts along with the fork all changed.
