I've started three businesses. One was the first company to commercially build artificial climbing walls in the USA. The next was a guide service for cross country skiers in the Canadian Rockies. The third was a short lived magazine that catered to traditional hot rodders. Every time I was early to the market and captured people's fascination with the "new" thing. The climbing business ended by being bought out for mucho $$$. The skiing was too risky and couldn't support decent insurance. The magazine was too much work.
Now I have rent houses and piddle around at Vorshlag.
