While walking the aisles of our local gun show today all of a sudden there was a loud "BOOM"! Of course, the floor got so silent you could hear a pin drop if not for the sound of feet hitting the ground as people rushed to the area where it came from. There was a good crowd around one table a few rows away from me. Then some laughter. Then the announcement that it was...believe it or not...a BLOWOUT from one of those big baby stroller tires! I did not even know baby stroller tires were air filled (guess I am showing my age). Anyhow, the whole floor had a good laugh, although for about 30 seconds or so after it happened it was not funny at all. That sound was loud in a closed in building.
