San Diego (Encinitas) to Borrego Springs...
Looks like 76 and 78 are the two options. Either way it looks pretty hairy at the end.

I found this via a web search and am going this route.
Safest route would be to try to avoid Montezuma Valley Rd. and/or Banner Grade.
1. Take I-15 North to HWY 76 – 15.3 mi. - Head East (Right)
2. Take Hwy 76 to Hwy 79 – 34.5 mi. - Head North (Left)
3. Turn right on S2 – 4.3 mi. - (San Felipe Rd.)
4. Take S2 to Hwy 78 – 16.8 mi. - (Turn Left)
5. Take Hwy 78 to Borrego Springs Rd. - 15.4 mi. - (Turn Left)
6. Borrego Springs Rd. will take you into Borrego Springs - 11.5 mi.
