Same thing happened to me Wed. nite at a local UDL - just curiosity bumps but they wouldn't commit and seal the deal - so don't feel like the Lone Ranger.
At least I stayed until 4 AM to be sure they weren't interested

Man, the next day was not pretty.
You can go through all the conjecture about the reasons - presence of bait - too much or too little, water temps, plug color and selection - it's a long list and doesn't end there.
Beats me, I couldn't pin it on anything I'd want to bet the mortgage payment on.
