Here's the scoop...
The CORRECT link for this festival is http://mandolinfarmbluegrass.net/
The old web site(s) was maintained by another party who is now using the old site(s) to sell tickets that will never be delivered to the purchaser. DO NOT purchase tickets through these web sites.
If you are a musician and are scheduled to play this festival, please make sure you are NOT LINKED to http://www.mandolinfarm.com or http://www.mandolinfarm.net Again, DO NOT link to these sites. It is my understanding that this was a problem last year and some folks showed up for one of the "supposed" FREE days that were advertised on the fake sites. Lowell has no idea what the Jarrell's are doing "legally" to solve this, but for now we need to spread the word about the correct link.
