Altogether OHV ran 36 events this year, one third more than 2004. And while average attendance dropped from 66 to 63 this is insignificant in the light of changes in event types and the big/small mix. The important thing is that through innovative event formats to avoid over-burdening volunteers, we are able to expand our activities and have fun at the same time.
Here are some stats from those 36 events, alongside those from previous years. Our biggest participation since we've been counting in this way! And below is a list of the volunteers who made those events.
| Year | Traditional Events | Park/Street/Trail Events | Rogaines | MTB-Orienteering | Total |

| 2000 | 97 (10%) | 383 (40%) | 317 (33%) | 153 (16%) | 950 (100%) |

(A "participation" in most events is a person who starts. In 2003 we didn't count people in groups except for rogaines, so the figures for trad and park/trail events for that year are a bit low. Rogaines can be much more substantial efforts than orienteering, so one rogaine "participation" is counted for each person for each 3-hour block rounded to an integer. There were two rogaines with 6hr classes, but even if we counted each person at par instead of as 2, participation would still be 2146.)
