YES! It's very common anywhere around airports with much traffic. We see 
lots of it in the SF Bay area -- N5KO, W6RN, WB6RJH, and I are roughly 
20 miles from SJC (San Jose) 30 miles from SFO (San Francisco), a little 
farther from OAK (Oakland). There are other propagation-related causes 
for spreading signals.
