Wanna recommend a station location, do it here: http://www.bikearlington.com/pages/bikesharing/capital-bikeshare-crowdsourcing-map/ And I will echo the comments of the commentors: the location of the stations in arlington is excessively concentrated in corridors - this is a tax payer funded project that is benefiting the select few. Arlington needs to do a better job spreading this around - Shirlington - Lee Hwy near glebe - Columbia pike. As it is, this looks like a Yuppie premium.
To those complaining about it being concentrated in corridors. You have to give it time. Bikesharing works best when intensely concentrated. If all stations were 1/2 mile apart it would severely limit the effectiveness of the system. Crystal city and R-B are the sensible first choices because the bikes really supplement the metro presence. It's the same strategy throughout DC where the stations also haven't reached some of the further out areas. Soon you'll start seeing the plans for bikeshare cover columbia pike, shirlington and Lee hwy.
