Hole 4 got removed (the real short dinker hole that paralleled the road). I think they took 4's pad and moved it to 7 and made a short pad, although its not really that much shorter.
Yea new baskets are in and the 4 new holes are all on the west part of the course near the park entrance. These holes help improve the course flow because you actually end at the parking lot now instead of having to walk up the large hill after getting done with number 9. There are no signs in or numbers on the new baskets but after you play them once its pretty easy to figure out.
I just started playing disc golf last week and have played this course twice. It is a fun course, but it would be helpful if the signs were updated. Hole numbers and yardage would be nice. My first time there, I had to ask several times where the next whole was, especially since there is no hole 5.
