This is one of those weekends where there is so much going on, it's hard to know which way to go. One event that promises to be the start of something huge in the life of downtown Hannibal is the first Downtown Hannibal Art Fair. The Renaissance Hannibal has set up this weekend celebration of the arts as a way to bring folks to the downtown historic district and to put a big spotlight on the local arts community. Artists will be on Main Street from 10 to 5 Saturday and 10 to 4 Sunday. Saturday is also the Second Saturday Gallery Walk, from 5 to 8 p.m. Plus, a number of downtown establishments will be open with food and entertainment. If you haven't been to the downtown area lately, this weekend would be a good time to check it out.
