Some caches to celebrate the birthday of a caching friend/rival/accomplice
Simply answer the following question correctly to be rewarded with the coordinates for this cache.
On this day in 1982 (18th December) There was a flight readiness firing of Challenger's main engines, how long did this last?
A - 20 seconds - N 52° 24.725 W 000° 18.963 or
B - 20 minutes - N 52° 24.963 W 000° 18.725
A 10km (6mile) walk around the twin turbines at Hamerton. The turbines can be seen for almost the entire walk (weather permitting)!
The walk itself is predominantly on footpaths, bridleways and by-ways which can get a little muddy at times. There is some road walking on quiet country lanes.
Caches 4, 5 and 6 are not on the loop as the nearby landowner doesn't like caches too close to their house, so you'll have to do them as a driveby or as a long walk out and back.
The hides are mostly 'smalls' and are hidden to be found. Along the route you can also pick up a couple of Paul's "Winwick Wander" caches and "A Bridge Too Far" and take a slight diversion for a Dozen Dashes cache and a church micro.
