hello ek skies,
for this question i would have to say that you can probably walk to the shoreline and certainly you should be able to make it to mackenzie beach.
i don't think you can walk to the center of town though, that is something like 5 km. I mean for sure it is possible to eventually walk it but the airport is not close to the center of town.
i mean i suppose it is possible also for you to walk to the pacific shoreline from kansas city airport, but you get what i mean.
if you are looking for spotting activity definitely mackenzie beach is the place for you. at least for incoming traffic. most takeoffs take place in the other direction.
