We were going to talk about the pitfalls of spark plug replacement this week, but since our good friends at Rolling Thunder Cycles closed up shop after 45 years of service we thought it'd be better to have Gerard come on and make the announcement formally. Also talked about was Buc-ee's spicy beef jerky, the legendary RTC holiday parties, and how to physically close a working business that has "lots of stuff" to dispose of.
