I've been recently studying the GIF format (yes, I know I'm a geek, get over it). What you need to do is use photoshop or GIMP (or whatever else) and reduce the number of indexed colours to as little as possible. Bear in mind though, for images like OP's there's a wide variety of colours because it's a photo. GIF should generally be used for graphics with sharp lines and few colours. Logos etc. are perfect examples.
Anyway, if your current GIF uses 256 colours, don't bother taking it down to 250 colours. It'll reduce the file size by at most a couple of bytes. To save any real amount of data, you'd have to cut down to much less than 128 colours. File size difference between 128 and 256 colours is practically non existant.
Reducing the physical dimensions of your GIF is the easiest way to cut back big on the size.
GIF is over 20 years old now. Until someone accepts a reasonable replacement, we're not gonna see smaller animated image files. Even though GIF was built for animations, it wasn't optimized for it, that's why you have such big file sizes.
