Mayo Clinic Advances Understanding of Concussions in Motocross
Awareness of concussions among high school athletes playing football, hockey and other sports has increased dramatically in the past few years. Parents and coaches are beginning to understand the dangers associated with concussions. Now, new information is emerging about concussions in motocross riders, thanks to studies at Mayo Clinic in Rochester, Minnesota.

Special Events Calendar
When individuals and groups want to use public land and water for events, they must apply for use of that resource through the Iowa Department of Natural Resources. These events are compiled by the Special Events System and are displayed on a calendar of events. These events can be searched by type, location, and date.
To find events which may be of interest to you, please go to https://programs.iowadnr.gov/specialevents/.
Special Event Permits
The Iowa DNR is authorized to approve a club or individual to hold an organized special event (an organized race, exhibition, or demonstration of limited duration which is conducted according to a prearranged schedule and in which general public interest is manifested) within the state if the event is scheduled to be held on public land or public ice. The DNR shall designate the equipment and facilities necessary for safe operation of ATVs, ORVs, and off-road motorcycles, and for the safety of operators, participants, and observers.
Residents participating in a special event must display a current registration on their ATV, ORV, or off-highway motorcycle. Nonresidents must display a valid, Iowa nonresident user permit on their ATV, ORV, or off-highway motorcycle.
At least 30 days before the scheduled date of a special event, an application must be filed with the DNR using the Special Events web-based application found at https://programs.iowadnr.gov/specialevents/.
