It is Friday and Fridays are for fun. The weather is supposed to be cool this weekend which means great biking weather. The St. Paul bike classic is on Sunday. It is a fun event. I have attended several times over the years but will not be participating on Sunday. This year the event is limited to 2450 participants for safety reasons. There is no registration on the day of the event. There is plenty of biking though with trails all over the city and beyond. The trails are open 24 hours a day, seven days a week.
