Is the idea of a "honey hole" such as in gold mining, present in bitcoin mining?
No, the SHA2 hashing function is not vulnerable to any known attack that significantly reduces the difficulty of finding a block, but it is a highly random process.

Randomness is funny sometimes. Statistically it it works out to be even over a longer time period or larger population, but if you focus in on a small set of samples sometimes you see a cluster or a gap. This is why the estimated hash rate of the network on blockchain.info is woefully inaccurate on anything less than a multi-day average, and bitcoin is based on a 2 week correction period instead of a smaller number.

(which is why the unlucky miner can't expect to find 2 blocks quickly "because" he had a drought, and you should not expect a gap to "make up for" earlier luck, it's the  population that matters.)
