So if you want to write Floyd in jail here is the info.
“Floyd wants to share his ID info: ID# 01363917, Clark County Detention Ctr, 330 S Casino Center Blvd, Las Vegas NV 89101″Thanks @MsJackson
That address is for anyone who wants to send fan mail to Floyd. Send it to what we just tweeted and it will get to him. Thank you.”
