I realize that participating as a volunteer on trail work and/or at an event associated with it is a potentially hazardous activity. I agree to abide by any decision of a Portland Trails staff person relative to my ability to participate. I assume all risks associated with volunteering including, but not limited to, falls, contact with other volunteers/participants, the effects of weather including high heat or humidity; and all such risks being known and appreciated by me. Having read this waiver and knowing these facts, and in consideration of your accepting my volunteer involvement, I, for myself and anyone entitled to act on my behalf, waive and release Portland Trails and sponsors, coordinating groups and any individuals associated with this volunteer work, their representatives, successors and assigns, and will hold them harmless from all claims or liabilities of any kind arising out of my participation. I grant permission to all of the foregoing to use any photographs taken during trail work events for any legitimate purpose. I understand that I must be at least age 18 or be accompanied by a guardian in order to volunteer.
