This is true in almost every major metro area. I help found an
exchange point in St. Louis. Not MAE-East levels of traffic, the
exchange peak at about 2.4 Mbps of traffic (more than a T1's worth).

travel 2,000 miles to get across town.
Of course, not every local ISP participates. The state subsidized
education network doesn't connect, nor do some the dialup ISPs. But
it gets a reasonable level of support from several of the larger
But exchange points are one of those weird creatures. If I'm paying
a big expensive backbone, why would I get anything from a local exchange
point? And of course, the ever popular "What's the catch?" Since
local exchange points are generally run on a non-profit basis, that
means there isn't a large marketing organization, or a huge gaggle of
salespeople trying to sell it. If you like, we can call it a "managed
connection" and charge you $1,000/month. But that seems steep for
essentially a port on a catalyst switch.
But we've found once an ISP connects, they generally keep it.
