I think you have a good point - cities might be statistically similar but getting out to another city might help in stepping out of your usual circle, which is not to say you cannot do the same while staying in your hometown.

Side note: This reminds me of a conversation I had with Wesley Zhao, a co-founder of Family Leaf, who said he finds it refreshing to hang out with normals while working on Family Leaf in Palo Alto. It's great advice for a tech founders to actively seek this out IMO.
