Roger:

I have really enjoyed the aerial photos you have posted. I noticed that the Feds have promulgated a rule requiring drones to be registered. I'm also wondering whether at some point in time the National Park Service will ban drones from all or parts of the park. I've yet to encounter one in a NP, but can foresee it becoming a potential controversy. Don't know how I feel about a ban, but I think that at a minimum, a permit system would be in order.

The C&TSRR route is sufficiently isolated that the chances of your drone activities bothering anyone are slim to none. Not to mention the fact that I don't think you're the type to be careless or inconsiderate anyway.
