Sometimes you may see one or two. Usually visiting from SF, Vegas, Sacremento, etc. One place I checked was Craigslist.Reno and EROS.com for that area. I didn't find a club or was able to meet anyone at a bar. Pickin's seem thin!!!
True that Rico, Vegas Lounge on Karen Street (starts on north side of the Holiday Inn with the Star Trek exhibition show). The mix of TGirls suits all tastes. Asian ladyboys were the slimest group the last three years I visited.
