Thankfully I'm blessed with an awesome day job that pays the bills and has unlimited flexibility on both how many days I take off and when I take off. So, my chase season is always determined by 1.) the quality of the season and 2.) available funds. With the car problem and distance covered in 2006, I'm still paying off this season. How much I progress on that and am able to save for 2007 will play a big role on how much I do next spring.
Lord willing and finances allowing, another 2003/2004-type season will get me out for a month or more solid, or as long as the active days continue. A 2001/2005-like year I'll just do several marathon trips on the bigger setups, then go home between them. Another 2002/2006-like year will keep me on day trips to Midwest targets (IL/IN) only.
I plan to pay setups in the closer-to-home Midwest much more attention in 2007.
