We would always stop by Knott's Berry Farm on our
Disneyland trips when I was younger. Went a few times with friends in my younger days, and the last few times were very disappointing. I haven't been there in over 7 years, but the last few times the parked seemed really run down and had a very "ghetto" feeling and atmosphere. I went to school with a girl who worked there, and she had nothing but bad things to say about the park and its guests - too many thuggy types and gang members.
RanCan sounds like you go often? What's your opinion of the park these days? My friend has a 5 year old, we're both disappointed with the park but would like to give it another chance so her son can check it out.
Oh and no, I would be against Disneyland purchasing Knott's Berry Farm. They've got their hands full already trying to make California Adventures better and more popular.
