A micro-cache, well-hidden in downtown Reading, near the old (now closed) post office building. Muggle traffic can be heavy at times, so be on the lookout and be prepared with your best stealth skills.
On-street parking is available. Log only, so BYOP. Placed with permission.
Update (April 2019): The original cache had to be moved because of construction. The replacement cache then went missing in its new location (likely muggled). So I have replaced this cache with a different type of hide in a nearby location. I am keeping the original difficulty and terrain ratings so that previous finders' statistics won't be affected. However, it may be a bit less tricky than the original hide, and although it is still technically wheelchair-accessible, it would probably be more difficult from a wheelchair than the original hide.
