Seeking 2-4 other riders to do this trip with unsupported in late summer (late August/early September or later in September but can consider other dates) to avoid rainy season.
I am 51, male, been cycling for nearly 30 years and have some experience with bike trips (Oregon supported trip, GAP-C&O Canal unsupported, plus weekend bikepacking trips).
I am flexible on lodging (can be a mix of indoors and camping or only indoors or mostly camping with some indoors every every 2-3 days).
