Online reviews describe Pulse as a friendly place that welcomed different ethnic and gender constituencies, as clubs in smaller cities often must-they become catch-all gathering points as matters of need and of business. By all accounts, Pulse was a typical gay club of size: chintzy-chic décor, go-go dancers and drag shows, three distinct music areas with names like “Jewel Box” and “Adonis Room,” and theme nights like “Dorm Wednesdays” and “Platinum Fridays.” Saturday was “Upscale Latin” night, a detail that should be marked as we mourn with the local community.
