My Dad is leading two trips through ABDNHA and there is room for anyone who wishes to attend. He's also looking for someone to pre-run both routes.
The Calcite Mine is Thursday, March 9th.
Dos Cabezas is Sunday March 26th.
If anyone is interested in the trips or the pre-runs let me know and I will get you the info. It's no cost through ABDNHA. He's providing BBQ and is asking whoever is in attendance to bring a side dish for the potluck for both trips.
