Bass Pro Shops posts a calendar full of FREE classes and workshops on fishing, camping, boating, hunting and other outdoor skills. We often check it out, but anglers might want to pay particular attention to this weekend. Saturday & Sunday, March 8 & 9, from 11 a.m. to 5 p.m., the store is running back-to-back fishing seminars. Topics include Walleye techniques for southern waters, ice fishing, and muskie techniques. The first 25 people to attend a seminar on Saturday or Sunday receive a FREE Bass Pro Shops insulated mug. 7970 Northfield Blvd., Denver, 720-385-3600.
