My daughter recently moved to Omaha.  I remembered that NE was often a troublesome section to find so with her permission I set up there for the 2015 CW sweepstakes.  The antenna is a Field Day variety push-up mast with wire dipoles, not terrific but efficient.  The weather in Omaha was perfect.  I didn't hear a peep out of EWA or AB.  Other than that it was great fun.
