In the past, I've used naming methods like this, and at first, it seemed really intuitive. But it becomes unnecessarily dense over time, and often results in awkward readability.

I've moved instead to simply using reasonably descriptive variable names where the type is easily inferred. The extra type information isn't missed.

  sZipCode = "90210"

really isn't necessary. Instead:

  zipCode = "90210"

works just fine. And leaving out the type information for a variable with no repercussions is 95% of use cases for variables.
