I dont have pics, and have never been there, but a quickGoogle seach found all kinds of pics and vids:
Here's a six min vid of several races there, crashes, interviews, closeups of all the old pros. Really good racing highlights!
About min 6 shows Chandler winning the 82 USGP.

(pasting the link does not seem to work. You may have to type it in).
There are a few other vids, too. Look for "Videos in this Gallery".
The vid starts with a 15 sec MSR ad featuring Grant Langston.
