SFMM wanted Goliath as near the front of the park as possible, so it could be seen by traffic on the I-5. There is all kinds of space around SFMM, trouble it is all owned by farmers who realize that suddenly their land is worth a pretty penny, should the mountain want to purchase more land.
CP is a big park, no space problems there. Any coaster, any size could easily be put in without any problems.
