Try google maps for a decent satellite pic. Summit to Central Ave, head east, runs right into a public launch, very small, limited parking, next to the 3 Bananas eatery. The Sunrise park above is like 100 yards around the corner.

If your a real early bird, the public launch works fine for most of my launches. After light, parking jockeying should be anticipated in a small lot. Sunrise is a larger facility, parking and launch wise, but I'm unsure if it's open 24/7.

Good luck / safe launches.
