How do spiders cast web across a long distance?

I'm sure my terminology is laughably wrong, but I'll try to explain best I can. For example, I'm walking down a twenty foot wide trail and walk through a spider web. How did the spider manage to cast its web over such a long distance? Is it on a tree on one side if the trail, anchors its web, crawls down the tree, across the trail, and up another tree? Does it anchor it's web and jump across? 

Does this make any sense or do I sound like a babbling stoner?

Some googling tells me that they stay on one end and start letting out some light web that gets caught in the wind and hopefully sticks to something at which point they reinforce it and begin making the web.
