Ch5 is a good propagation indicator for Mexico and Central America, as it's used like our Ch19 - by the majority of their truckers.
Of course, Da 'Bowl is usually open to somewhere and is a good gauge of single-hop Es.
Ditto Ch38 LSB.
For those with Browning Marks, Tram Titan/D-201 series, a general coverage receiver or a freeked-n-peaked CB/"export" set, head on up to 27.555USB and listen for DX spots.
Those with general-coverage receivers or other gear which tunes below Ch1 can listen for the Spanish version of Da 'Bowl on 26.705, various SSB nets on 26.555/.585 and the southern states DXing and rag chewing on 26.915.
There's always something doing on 11M. But lately I've been seeing a big uptick in MURS usage by the former CB crowd. Availability of rigs such as the R/S 19-1210 and the freedom to use a gain-type, external antenna has resulted in many people adopting the "dot" frequencies as a go-to allocation.
