Some ideas that can help are:
- Different texture ropes strung between buildings with different numbers of knots tied at important locations.
- Different texture gravel and stone paths to different locations.
- A contrast of lighting brightness or colors.
- A talking Trekker GPS can be programmed with destination points and routes around the ranch. Contact Humanware at www.humanware.com or phone at 800-722-3393.
- High visibility tape or paint to mark paths, buildings and other locations.
- One farmer reported using different sounding wind chimes to identify key sites around his farm.
- Another farmer used radios set to different stations in his garage, shop and barn to help give him his bearings.
- Breaking New Ground Resource Center at Purdue University has an entry in its Plowshares Technical Reports series that you might find beneficial—Farming with a Visual Impairment (Plowshares #13).
- The "Toolbox," is a CD-ROM and on-line catalog of commercial and farmer-modified equipment and assistive devices for farming with a disability. One of the "Toolbox" fact sheets is on outdoor navigation aids for the visually impaired. Your county Extension office and local high school agricultural education teacher should have a copy of the CD to view (perhaps borrow), or you can access it (in pdf format) at www.bngtoolbox.info.
