During the beach scene, Travis is talking to his girlfriend. Over their shoulders you can see cliffs. There are no cliffs in the SW Florida area. The Venice Beach area, which is presumed to be the location, has more shells than sand.
The photo Travis finds in Jules' (Courtney Cox) High School Yearbook of her on stage with Bruce Springsteen is from Springsteen's video of "Dancing in the Dark" made in 1984, when Courtney Cox was barely 20 and long before she became a star in Friends.
In the Friends episode The One Where Ross Finds Out (1995), Monica's (played by Courtney Cox) brother Ross accidentally finds out that she's dating Chandler.
