EGCA
GA traffic is around everyday at DSA along with military aircraft. Its not actively encouraged and they are not allowed to base at the airport but they do appear once or twice a day. Movement lists can be found on the Yahoo DSA group, egcn website and various other sites if you are interested in what comes in.
The local GA fields are fairly busy and as you would expect there are some misunderstandings between all parties concerned in the local approach airspace, as there is no controlled airspace between the numerous fields in the close area.
