The currently proposed field limit for the W3/4 road race at McLane is 100. I think that it might make for a safer and better race if it was at most 75. There are two main (related) issues:
1) Not all of those riders have great bike handling skills, particularly early in the season. That course is not extremely selective, so a big field will probably stay big.
2) With the large number of groups on the course, and the expected slower pace of the W3/4 race, it is a virtual certainty that they will be overtaken by both the P/1 and cat.2 men - both of which have big, fast fields with accompanying cars. The neutralizations are bad enough, but having a bigger field to squeeze over near the shoulder may be more hazardous.
