I would like to know the best way to increase the amount of hotspots I can see.  I assume I will take the approch wardialers do?  get some type of hi gain attena and attach it to access point?  or just attena to pda? I would like to be able to sit in a parking lot of a restraunt etc and get their signal.  Also more signals means more likly that I can find an avalible open network at any given spot. seems most people have at least wep in a given area (Even though war dialers say opposite)  it would be nice to find a public connection through all the others
