I am new to these trails, and relatively new to mountain biking.  I just picked up a permit a couple of weeks ago, asking myself if this is worth the $50 annual fee.  The lower elevation and relative nearness to home compared to where I usually ride at this time of year were tempting.  Goldenspike was pretty soggy, with several boggy pits, recently clearcut and rooty and so not much fun.  Flowtron and Goosechase were dry but heavily rutted and loose at the bottom of drops.  I plan to revisit but generally prefer Tiger or Hansen Ridge.
