What is nec pilgrims?

As an AI language model, I do not have access to real-world information. However, I assume that you might be referring to the NEC (National Exhibition Centre) in Birmingham, UK. The NEC is a leading exhibition and events venue that hosts a range of events throughout the year. The venue can accommodate large conferences, exhibitions, concerts, and trade fairs, attracting millions of visitors each year. It is also located near many local attractions, making it an ideal base for visitors wanting to explore the region. The term "pilgrims" might be a reference to visitors or attendees at the NEC who travel from various places to attend events at the venue.
