Every year, they have had the border that is currently displayed in some form.

In 2008, there was indeed a larger wall, near the overpass. There was also a center divider, if you'll recall. The purpose was to keep the folks that were right there from the effects of a missed hurdle, as running is a bit harder if you've got a scoring device in hand or on the table in front of you. The fence used was not attached to the field border in any way, shape, or form, save some zipties between members at passing points.

In 2006 and 2009, no such walls existed; the standard field border was deemed sufficient. In the rare cases it wasn't, a field reset person would give chase to the offending ball.
