Heads is now an even shorter price and represents no value. Tails now stands at a slightly better price but still only represents 'true odds' or likelihood of winning at 1/1 or 50% and so is not value.

The event continues and still betting favors heads. Why? Well 'average bettor' does not really understand 'value', he does not understand that heads might well be a bad bet or hold no value. He just enjoys betting and since 'heads' is winning - he wants to bet on heads.

The bookmaker balances his books again with a dramatic shortening of odds for heads to 4/9 and a lengthening to 6/4 on tails.

At this point professional bettor would step in and begin to place bets on tails. He knows that he has got value at 6/4 (+150 US), for an event where 'true odds’ of success are 1/1.

As long as he bets at this price (6/4) or any 'value' price, professional will win in long run.

Naturally, it is not as easy to assess 'true odds' in sports events because there are so many variables, however, with experience it can be done, especially if one specializes in particular sports events.

Wheels In Nature, or WIN, brings children and adults in wheelchairs together with those who aren't through muscle powered outdoor adventures. Each summer, WIN conducts youth camps in kayaking, wheelchair court sports and racing, sailing, fishing, hand cycling, and a special Arts In Nature Day. Longer outings include day trips to wildlife refuges and overnight campouts in some of Oregon's national forests.

Funding for WWS is provided through membership and entry fees, donations, and grants. Members come from many different backgrounds and levels of disability. Hansen, who became a quadriplegic following a snow skiing accident, thought his athletic days were over until he was able to acquire one of first lightweight aluminum sports chairs to be mass-produced in U.S.

"That chair got me into road races and track meets, and was first of many equipment upgrades," he says.

Some participants are older people who suffered a stroke or severe arthritis, while others were born with disabling conditions that left them paraplegics or double amputees. But thanks to programs of World Wheelchair Sports, these individuals can experience thrill of athletic competition, or freedom to enjoy recreational activities in a more relaxed environment. The chance to share these experiences with those who are not in a wheelchair gives them an even greater feeling of satisfaction and accomplishment.
