In the latter years of the park, a Wildcat roller coaster was installed around where the lagoon is currently on the site, not far from Bardol Avenue. If you look closely at the photo above, available for purchase on eBay (nothing to do with me), you can see homes on Bardol as they appeared in the late 1920s.
If you click on the colour photo below you can see several photos of a Wildcat located at Hersheypark Amusement Park in Pennsylvania. There are also a number of videos of various Wild Cat coasters to give you an idea of what a ride on the giant wooden roller coaster would have been like (note that there appear to be various designs using the Wildcat name over the years).
There are still a few people around who rode the Erie Beach Wildcat -- if you are one of them please email me.
