I've done bayside and I've not done bayside... not sure I really care either way. Same with Cliff but that was on there already from last time so I left it. We can certainly do it!
We'll need to remember to check the train schedule the week prior to make sure metro isn't doing any silly maintenance. Also, our trip is smack between two military exercises - I assume the bike path adjacent to the base will be open. I'm OK with the 8 miles between Las Pulgas and Harbor but I'm really not interested in doing any more than that.
