Did you hear these?

By "these" is meant a series of loud reports, between approximately 4:15 and 4:30 am this morning (Sunday, 30 January). If you did hear anything, you'll know what I'm talking about. The location was somewhere between IH-35 and Congress, along Riverside, part or all of that distance. If you have information about this incident, you may call 3-1-1 or Austin Police Department South Central District Representative James Scott (telephone 448-4385).
