As did a number of people as most of the neighborhood were up in pretty short order after the quake (I could see a number of TV's on, trying to watch the news). The timing was also too perfect to be coincidence, twice.

      The fact is a quake's ability to shake things over distance depends precisely on what the ground is made of. Some materials soak up the shockwaves quickly (like the rocks of California), whereas others will transmit the waves over massive distances with very little dissipation (like the rocks in the Midwest). There are a lot more factors than just distance and even rock consitution, but you get my drift.

      At the epicenter, it was a 5.2. On instruments in downtown St. Louis it registered 5.1 at its peak and rumbled for up to two minutes from the initial shock. That's 140 miles as the crow flies and little to no dissipation.

      Now, another friend of mine who works at the USGS in Rolla, MO (about another 70 miles) says they picked up barely 4.0, so it's clear it dissipated quickly through Missouri but transmitted nicely through Illinois.
