I've seen a couple of launches from Vandy while visiting the LA area. The early evening launch on Dec 22, 2017 was totally awesome. It was even visible from Phoenix. I saw a daytime launch and there wasn't much to see other than a vapor trail...
i am viewing the launches from bakersfield, day launches can see flight thru staging then lost in the suns glare, night launches are the best, can see 2nd stage all the way south till the horizon.
