In recent years progress has been very slow so I don't see my WAS being finished any time soon. Perhaps there is some resource on the web that could assist me with arrangements for the remaining states, or even some readers in these states who would help me?
I thought initially that Alaska and Hawaii would be hard, but they were not. Instead the hard ones have turned out to be the 9 grey/red states in the map: North Dakota, South Dakota, Kansas, Oklahoma, Idaho, Nevada, Utah, Wyoming, and Oregon. The two last ones are unconfirmed so that is why they are red.
The most successful bands for me have been 20 m and 15 m and the best opportunity for new states has been the ARRL DX contest in February each year, but maybe next weekend's CQ WPX contest also will help.
