In the folding bike subculture, there exists a subculture of foldie riders called TSP or TIKLOP SOCIETY OF THE PHILIPPINES. I usually ride alone... but on one Thursday night in April, I joined their weekly Thursday night ride around UP. Actually, I joined the tail end of their ride and rode with them to dinner.
It's fun seeing a group of riders riding at night, specially if you're at the back. Why? Because of all those blinking lights. It was like Christmas in the middle of summer. And, it kind of makes you wish you took a mind altering substance so you could enjoy the lights more.
