Unfortunately, Illiniwek is a no go for bikes this weekend. Just checked the northern facing trails (ones getting the least sun) and they are softer/muddier than last week thanks to overnight freezing the last couple of days. There have been people out riding them and leaving ruts already... Please stay off the trails until they have firmed up enough to prevent this. Other local trails are having better luck and dryer conditions so there are options for riding trails this weekend which is still highly unusual this early in the season.
