To get the next (L)NERD clue, Lou needs to go to the location South GB HI.UPK East AMK BP.PLC or you could also try Googling JIQEE
Lou notes that the first parts of the final Location are South RB East JRK . All clues in this (L)NERD cache are presented in the same format.
At the next location, Lou finds a Quick Response code that requires being read on his smartphone FRED. This code looks like nothing much, but when read correctly, provides the location of the next (L)NERD clue and some S minute data for the final location. Lou ducks across the road for a bit of Salami. You can too if you like. It is not a part of the cache journey.
Along the way, Lou discovers that you can use colours to hide numbers, and he finds this (L)NERD approach irresistible. Lou also discovers that each location being visited on this (L)NERD Journey has a unique number which defines the location. After a bit of exercise Lou heads off to the next (L)NERD discovery. The clue here gives the next location and some E minute data for the final location. After doing a quick bit of shopping Lou heads off to the next location.
Lou then gets to the next (L)NERD location, where he discovers barcodes that can hide numbers in plain sight that once again need to be read on his smartphone FRED. After this discovery, the next location is uncovered, along with some S decimal minute information for the final location.
At the last location Lou visits, he discovers Ciphers where information is hidden using various methods to hide and confuse people. Lou starts with a simple and commonly used cipher, and said HI Caesar. Try converting this using FRED and see what you get. At this (L)NERD location you will find the last of the E decimal minute location for the cache location.
So, now armed with all the information obtained, Lou puts it all together and travels to the end of the (L)NERD cache to locate a container and sign a logbook.
As always, please take care at all locations while gathering information.
