Yes the Silo looks kinda spooky at it's location, but that is why its the only one in the area that still has GHs. It does not draw much attention to itself like the Cupids do with their neon lights.
It is owned by the guy who used to have a similar place on Asher many years ago called "Ladies World".
A little steep $$ to get in, particularly when its dead
but the flip side is that you can stay for several hours if you wanna.
Best times are lunchtime and early afternoons weekdays, mid day and late night for weekends, etc., but its a great place for an arranged meeting mid-morning.
We have had several mid-morning "suckfest" with 5-6 guys who plan on being there at the same time.
