I'm not really a big fan of theme parks, mainly because of their
bloody expensive admission fees and long queues for the
rides.
I've been to the Disneyland in Anaheim, CA, mainly because one of
my sisters lives just 10 minutes from it (and yes, she can see
and hear the fireworks
display that they put on every night). I've also been to Magic
Mountain and Knotts Berry Farm in previous years.
Here in MN, we have Valleyfair, which I've been to a
couple of times. Same thing: steep admission rates and long lines
for the rides.
