Event Write-Up

By , Event Director

Two smooth running days in a row resulted in a great weekend in the Marin watershed! First-time course setter Johanna Merriss designed challenging, yet fair courses, which took great advantage of the variety and beauty of the terrain. The courses wound through the scenic landscape, visiting not only the “Hillside of Death”, but also the southwest peninsula, which has been out of bounds to us until recently. Johanna’s courses led participants through all the different ecosystems, offering tough route-choice decisions on some legs, and opportunities (not always taken) to enjoy the scenic beauty as well.

Club volunteers, as well as a couple of foreign orienteers in the area on vacation, enjoyed the courses, the fine weather, and the various delectable munchies arrayed at the event headquarters.

Bon Tempe offers some of the finest (in my opinion) terrain the Bay Area has to offer. It is a shame that we aren’t allowed to host full-sized events there!

The event would not have run smoothly without the help of many people. Laurie Offenbach at MMWD made getting the permit an easy task, while BAOC’s Marina Keating acquired the necessary insurance documents. Jeff Lanam trained me on the E-punch system, allowing me to run it all weekend without my crashing the system! Thanks to those who brought food to share​—​we had a feast, and very little left over by the end of day on Sunday.

Finally, near and dear to an Event Director’s heart, I want to thank the Control Pick-up crew of Bill Cusworth, Theo Verhoeven, Julia Doubson, Fyodor Konkov, and Tom De Vre, for collecting the controls quickly and letting us all head for home by 3 PM!

Thanks to all involved for making this year’s event a great one!
