Narrative:

I misread the distance from the location of my hobbyist uas training flight and was about 4 miles from high view airport; a private; non-towered airport in northern virginia; approximately 10 nm south of mrb. I had tried to contact the owner of the airport previously in order to discuss contacting him if need be and never received a response from him. There are actually two other private airports in the immediate vicinity of high view; but they are not charted on the washington sectional. They are actually busier than high view which sees very little activity. None of the three have more than 1 or two flights per week that I can tell. I went back to the area I flew and used the B4UFly app and discovered my measurement error.there does not seem to be a good way to find contact information for private airports. None appear in the FAA's chart supplement book (formerly airport facility directory) and I cannot find contact info on web based programs like foreflight. If the FAA is going to require notification of private airports (as this showed up on B4UFly); we need a source of contact information. I just happened to know the owner of high view and as stated before had tried unsuccessfully to contact him.
