I've ordered a camera for my phantom and intend to enjoy taking pictures, but I was wondering if anyone has found a regular use for them besides photography? I thought originally there would be a chance they could be used for geocaching, e.g. maybe dropping a microcache onto an island in a lake (from the shore) or up a tall tree but my initial practice runs have not made that look feasible. Are there any kinds of contests, challenges, or other recreational uses? So far I have not met anyone in my area who has one but if nothing else I think they could serve as a good uniter for a club of some sort.
