Are you talking about 35mm rolls that were exposed 30 years ago or 30 year old film that you used recently?
Also, was it refrigerated? (or hopefully frozen?)
Gordon's is your only option for local service. Fortunately, it's also a good option. They do good work.
Walmart uses Fuji Labs if you send it out with their mailers. That's a good option and it's inexpensive. NEVER use Walmart 1-hour processing.
No the film was developed and I have the negatives. I'll give Gordon's a try.
