The cache IS at the posted coordinates. But you must meet the challenge qualifications before you claim your find.
Credit for the idea behind this challenge goes to [JJDP].
My wife and I love virtuals and we often go miles out of our way to get one along the way. This challenge is simple: find 10 virtual geocaches in 5 different states. Finds are cumulative and there is no time restriction. The District of Columbia does NOT count as a state for this challenge. The cache is rated given the difficulty to get all of those finds. The challenge cache itself is probably a D/T of 1.5/1.5.You may sign the log any time, but only claim the find when you meet the requirements. BYOP.
