Successful-Test-5590's journey

I have an interview scheduled for a position that is about 20 miles away this Thursday. I'm feeling uncertain because I reached out to the hiring manager about the salary but haven’t received a response yet. The salary details weren't mentioned during the initial screening, and it wasn't listed in the job ad either. I'm hesitant to spend money on an Uber to get there if the salary ends up being too low. I’m also concerned about the lack of communication; it feels a bit off to me that she's ignoring my email before the interview. I live in Texas, where it's common for companies to avoid disclosing salary information. I'm wondering if I should still go to the interview or if it’s a red flag.
