You don't need to be in a RACE to find this cache. If you bring the kids, you might need to plan on spending some time here, because it would be very easy for them to find fun things to do around here - especially in summer when it's hot. There are also things to do for older kids or just those who are young-at-heart.
The water that this cache is under is hard to miss since you can see it from quite some distance away.
The cache is an uncamouflaged water-proof small container, it has room for only very small swaps. Take care with the inhabitants often found lurking inside a hiding place like this one.
This area can be very busy, so please be aware of muggles who have easy views from all directions, visiting outside of school holidays or peak times would be a good idea. Parking as close as possible to GZ should provide good cover/excuse to help while looking for the cache - when you visit might determine how wet the car gets.
