Rookie Mistake with Memory Palace?

So, going along nicely with memory palaces and without understanding why I hit a block. Memorised a row 14 of nearby streets (Chester, Princess, Bishop, etc) by creating a solid story linking the streets.

I then used these street names as a palace to attach lines of poetry. This doesn’t work!

On these streets is a point; church, school, store, etc. I memorised these points as a palace and attached lines of poetry to them. That always works.

Best guess is street names are just a random collection of letters and don’t work as well as ‘points’.
