Green day 1 at Buttes Pass in Anza-Borrego S.P., east of the camping area. Thanks to Bill Gookin this park is VERY well mapped and if you took your time you could navigate well. Spur areas covered with small rocks were more stable than the reentrants between them where the rocks loosened from the soil and slipped out from under you -- I quickly learned to stay on top of the spurs. Oh, and I quickly learned to watch carefully for the teddy-bear cholla
, too, which was ubiquitous, but scattered so you could pick your way around it. Beware if you look down at your map, however!
I was off about 50 meters to the right to the first control (I was busy getting used to the map and crossed the proper spur at a slightly wrong angle, but saw someone punching the flag to my left). As I was a later starter, I also had help along the way seeing people going into the control area, from a good distance, despite not being able to see the control. The second half of the course got into more hilly badlands (steep spurs/reentrants) requiring more leg strength and attention to avoid parallel errors. On leg 9-10, rather than taking the obvious safe route to the road and then along a spur to the control, I chose a different reentrant route which required more effort and a difficult descent, so it was much slower; I probably lost 5-7 minutes on that leg (if not more).
